bimetallic powders -- gold-palladium -- redox potential
Аннотация: The redox potential of fine-dispersed and compact bimetallic powders of the palladium-gold system in hydrochloric acid solutions of H2PdCl4 at a temperature of 60A degrees C was studied. It was found that the redox potential increases with gold enrichment of the solid solution in accordance with the Nernst equation. The effect of gold-palladium particle size on this redox potential is shown. The morphology, sizes, and composition of bimetallic particles are determined via transmission electron microscopy and X-ray diffraction analysis.

Аннотация: The reduction of chlorocomplexes of gold(III) from muriatic solutions by nanocrystal powders of palladium and platinum at 110 and 130 degrees C under hydrothermal conditions and the action of microwave irradiation has been investigated. The structure and composition of the solid phase have been characterized by transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and chemical methods. Bimetallic particles with a core-shell structure have been revealed. The obtained particles are established to have a core of the metal reductant covered with a substitutional solid (Au, Pd) solution in case of palladium, and isolated by a gold layer in the case of platinum. The main reason for such a difference is the ratio between the rates of aggregation and reduction. It has been shown by the example of the Au-Pd system that the use of microwave irradiation allows us not only to accelerate the synthesis of particles but also to obtain more homogeneous materials in comparison with conventional heating.

Treatment of the synthesized complexes with [Fe2(CO)9] led to mixtures of [Cp(CO)2ReFe(μ-CCHPh)(CO)4] (5), [(dppe)PdFe2(CO)8] (6), [CpReFe2(μ3-CCHPh)(CO)8] (7), [CpReFePd(μ3-CCHPh)(CO)5(dppe)] (8) and of 5, [(dppp)PdFe2(CO)8] (9), [CpReFePd(μ3-CCHPh)(CO)5(dppp)] (10), respectively. The main products of both reactions were trinuclear μ3-vinylidene clusters 8 and 10. Reactions of the trinuclear μ3-vinylidene ReFePd clusters 8 and 10 with Fe2(CO)9 were also studied. New complexes were characterized by IR, 1H, 13C, 31P NMR spectroscopy and cyclic voltammetry. The structure of [CpReFe2(μ3-CCHPh)(CO)8] was determined by single-crystal X-ray diffraction.

Surface modification of detonation nanodiamonds with platinum and palladium nanoparticles / V. G. Isakova [et al.] // Int. J. Chem. - 2015. - Vol. 7, No. 1. - P. 1-9, DOI 10.5539/ijc.v7n1p1. - Cited References: 38 . - ISSN 1916-9698

detonation-synthesized nanodiamond supports -- platinum and palladium nanoparticles -- combustion -- chemical modific -- DND additional purification
Аннотация: Acetylacetonates of platinum group metals (M(acac)n, acac= CH3COCHCOCH3,n - oxidation state of metal) are the most suitable precursors for use in highly effective MOCVD (metal-organic chemical vapor deposition) processes because of their thermal properties, low price of initial ligand and accessible synthesis methods. In this study we have developed a simple, scalable inexpensive, MOCVD-like approach to the deposition of Pt and Pd nanoparticle dispersions on powder detonation nanodiamonds (DND) using combustion in air of powder mixtures of DND with Pt and Pd acetylacetonates. This one-step process requires no specialized apparatus, and is conducted at mild temperatures (180°C – 250°C). The substrate surface of DND initiates chemical thermal destruction of precursor and deposition of nanoparticle networks composed of constituent particles. DND-supported Pd and Pt nanoparticles with their loading being from 10 and 5wt. % were obtained the average of particle size 20-25 nm and 7-10nm decreases with decreasing the metal loading. For additional purification and disaggregation of the commercial detonation-synthesized nanodiamond (DNDcomm) the method of annealing of the powder mixtures DNDcomm with Na(acac) have been used. The purified diamond nanoparticulates (DND), as well as DNDcomm, Pt/DND and Pd/DND, were subjected to physicochemical characterizations, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray (EDX) analysis.

Аннотация: We calculate the quasistatic electromagnetic density of states for aggregates of touching spheres, in particular, linear chains and computer-generated random fractal aggregates. Multipole moments with orders of up to L=64 are taken into account for random aggregates with the number of particles of up to N=100 and up to L=8000 for linear chains. Extensive comparisons with the dipole approximation and geometrical cluster renormalization method are performed. Extinction spectra are calculated for several metals and black carbon. Long wavelength electromagnetic properties of fractal aggregates are considered in details.

Аннотация: Adsorption complexes of palladium atoms on F-s, F-s(+), F-s(2+), and O2- centers of MgO(001) surface have been investigated with a gradient-corrected (Becke-Perdew) density functional method applied to embedded cluster models. This study presents the first application of a self-consistent hybrid quantum mechanical/molecular mechanical embedding approach where the defect-induced distortions are treated variationally and the environment is allowed to react on perturbations of a reference configuration describing the regular surface. The cluster models are embedded in an elastic polarizable environment which is described at the atomistic level using a shell model treatment of ionic polarizabilities. The frontier region that separates the quantum mechanical cluster and the classical environment is represented by pseudopotential centers without basis functions. Accounting in this way for the relaxation of the electronic structure of the adsorption complex results in energy corrections of 1.9 and 5.3 eV for electron affinities of the charged defects F-s(+) and F-s(2+), respectively, as compared to models with a bulk-terminated geometry. The relaxation increases the stability of the adsorption complex Pd/F-s by 0.4 eV and decreases the stability of the complex Pd/F-s(2+) by 1.0 eV, but it only weakly affects the binding energy of Pd/F-s(+). The calculations provide no indication that the metal species is oxidized, not even for the most electron deficient complex Pd/F-s(2+). The binding energy of the complex Pd/O2- is calculated at -1.4 eV, that of the complex Pd/F-s(2+) at -1.3 eV. The complexes Pd/F-s and Pd/F-s(+) exhibit notably higher binding energies, -2.5 and -4.0 eV, respectively; in these complexes, a covalent polar adsorption bond is formed, accompanied by donation of electronic density to the Pd 5s orbital.

Synthesis and catalytic hydrogenation activity of Pd and bimetallic Au–Pd nanoparticles supported on high-porosity carbon materials / O. V. Belousov [et al.] // React. Kinet. Mech. Catal. - 2019. - Vol. 127, Is. 1. - P. 25–39, DOI 10.1007/s11144-018-1430-0. - Cited References: 57 . - ISSN 1878-5190

MOCVD -- Hydrothermal synthesis -- Palladium nanoparticles -- Mesostructured carbon -- Bimetallic Pd–Au catalyst -- Furfural diethyl acetal -- Hydrogenation
Аннотация: The processes of palladium deposition on various high-porosity carbon matrices (Sibunit, CMK-3) have been studied. Mesostructured carbon material CMK-3 was synthesized using a silicate template of SBA-15 type. Pd nanoparticles were loaded onto carbon matrices by metalorganic chemical vapour deposition (MOCVD) method using palladium(II) acetylacetonate precursor. Bimetal Au–Pd systems were synthesized by autoclave reduction of gold(III) chloride complexes on Pd-containing carbon matrices. Structure of the obtained composite particles was studied by electron microscopy and X-ray diffraction. The average diameter of Pd particles on Sibunit is about 10, and 5–6 nm on CMK-3. The catalytic activity of the synthesized materials was studied in the reaction of furfural diethyl acetal (FDEA) hydrogenation, using gas–liquid chromatographic analysis. There is significant difference in catalytic activity of MOCVD-Pd/C compared to conventional impregnated Pd/C systems: the hydrogenation rate is 3–6 times higher with MOCVD-derived catalysts. Introducing Au into a MOCVD-Pd/C catalyst increases the hydrogenation rate threefold. Considerable difference in the composition of hydrogenation products was observed between these differently prepared catalysts.

carbon nanomaterials -- platinum metal nanoparticles -- in situ one-step method
Аннотация: Carbon nanomaterials (fullerite, detonation nanodiamonds, Taunit, fullerenol, fullerene-containing black) were decorated with platinum group metal nanoparticles in situ in one step by low-temperature combustion (~250–270°С) of a powdered mixture of platinum metal acetylacetonate [Pt-M(асас)n, Pt-М = Pt(II), Pd(II), Rh(III), Ir(III), acac = CH3COCHCOCH3, n is the oxidation state of Pt-М] with carbon nanomaterials in air. As shown by thermal analysis, the process is based on thermal oxidative degradation of the organometallic complex, catalyzed by carbon nanomaterials, with oxidation (combustion) of the organic moiety and release of the metal into the condensed phase. The thermal process in an open system occurs in the glowing mode (210–250°С); the size of the nanoparticles formed is 7–30 nm. Under the conditions restricting the air access to the reaction mixture and free outflow of gaseous products formed by oxidation of acac ligands, the nanoparticle size decreases to 3–10 nm. The particle size depends on the metal amount in the initial powder mixture and on the support morphology.

Аннотация: The ion exchange sorption of the platinum(IV) chloride complexes in the presence of silver(I) chloro complexes from 2 and 4 M aqueous solutions of hydrochloric acid is studied on Purolite anion exchangers with different functional groups. The high selectivity of the investigated sorbents with respect to platinum during its recovery from individual hydrochloric acid solutions and in the presence of silver chloride complexes is determined. Since the latter are in this case virtually not sorbed in the presence of platinum(IV), they can be separated at the stage of sorption. The excellent kinetic properties of the investigated anion exchangers are revealed, allowing platinum to be eluted after its separation from silver chloro complexes in a dynamic mode.

Аннотация: In this work, the effect of Pd, Au and PdAu nanoparticles on sensor response of cobalt phthalocyanine films to hydrogen was studied. For this purpose, novel heterostructures based on cobalt phthalocyanine and PdAu nanoalloys were obtained by a combination of vacuum thermal evaporation and pulsed metalorganic chemical vapor deposition (MOCVD) and investigated as active layers for hydrogen detection. The structural features and phase composition of the prepared heterostructures were studied by the techniques of X-ray diffraction, transmission electron microscopy and electron diffraction. The concentration of metal nanoparticles in the samples was determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES). The chemiresistive sensor response of CoPc/M (M = Pd, Au, Pd0.2Au0.8 and Pd0.8Au0.2) to hydrogen (100–400 ppm, room temperature) was compared with that of bare CoPc films. It was shown that the sensor response of the investigated heterostructures to hydrogen (300 ppm) increased in the order CoPc (0.2%) < CoPc/Pd0.2Au0.8 (1.9%) ~ CoPc/Au (2.2%) < CoPc/Pd (2.7%) < CoPc/Pd0.8Au0.2 (5.6%).

Аннотация: Features in the formation of chemically deposited polycrystalline Co-P films with thicknesses of a few nanometers are established by analyzing film surface morphology and variation in the film magnetization. It is shown that in the thickness range below 30 nm the polar Kerr effect value OK changes nonmonotonically and depends on a wavelength of the incident light. For the films thicker than 30 nm, this value depends weakly on both the thickness and the wavelength. These features in the OK behavior are attributed to the Faraday effect, which is revealed at small thicknesses upon light reflection from the lower surface of a magnetic layer. It is found that the Faraday effect in the Co-P films exceeds that in the Co films by a factor of more than two. This effect is assumed to be caused by the presence of a Pd underlayer in the samples under study. (C) 2011 Elsevier BY. All rights reserved.

Аннотация: The reactions of Cp(CO)(2)Re=C=CHPh (2) with M(PPh(3))(4) (M = Pd, Pt) gave the mu-vinylidene complexes Cp(CO)(2)RePd(mu-C=CHPh)(PPh(3))(2) (3) and Cp(CO)(2)RePt(mu-C=CHPh)(PPh(3))(2) (1), respectively. The substitution of Ph(2)PCH(2)PPh(2) (dppm) for the PPh(3) ligands in 1 resulted in the formation of Cp(CO)RePt(mu-C(1)=C(2)HPh)(mu-CO)(dppm) (4). The structure of complex 4 has been determined by single-crystal X-ray diffraction analysis. The structural and spectroscopic characteristics of complexes 1, 3, and 4 were compared with the corresponding parameters of the manganese-containing analogs Cp(CO)(2)MnPd(mu-C=CHPh)(PPh(3))(2) (5), Cp(CO)(2)MnPt(mu-C=CHPh)(PPh(3))(2) (6) and Cp(CO)(2)MnPt(mu-C=CHPh)(dppm) (7).

Negative area compressibility -- Lifshitz mechanism -- Charge transfer
Аннотация: Negative area compressibility (NAC) is a counterintutive “squeeze-expand” behavior in solids that is very rare but attractive due to possible pressure-response applications and coupling with rich physicochemical properties. Herein, NAC behavior is reported in palladium diselenide with a large magnitude and wide pressure range. We discover that, apart from the rigid flattening of layers that has been generally recognized, the unexpected giant NAC effect in PdSe2 largely comes from anomalous elongation of intralayer chemical bonds. Both structural variations are driven by intralayer-to-interlayer charge transfer with enhanced interlayer interactions under pressure. Our work updates the mechanical understanding of this anomaly and establishes a new guideline to explore novel compression-induced properties.
