, p. 1423 - 1429 (1997)
The thermal behaviour of the complexes of N,N-diethyl-N′-benzoylthiourea (DEBT) with Ni(II), Cu(II), Pt(II), Pd(II) and Ru(III) was studied using differential thermal analysis (DTA) and thermogravimetry (TG). These complexes undergo only a pyrolytic decomposition process. A gas chromatography-mass spectrometry combined system was used for the verification of the first decomposition product and X-ray diffraction method for the characterization of the final products of pyrolysis.

, p. 21 - 27 (1998)
The BaPdS2 mixed palladium sulfide has been synthesized by direct reaction of a stoichiometric mixture of the PdS and BaS binary constituent sulfides. The standard molar enthalpies of formation of BaPdS2 and LaPd3S4 mixed sulfides were determined by the method of direct reaction calorimetry through synthesizing the respective compounds in a calorimetric cell from the stoichiometric mixture of appropriate starting materials. Combining the experimental results with the reference data for the starting materials, we found Δf,298H0m(BaPdS 2)=-515.4±16.8 kJ mol-1; and Δf,298H0m(LaPd3S 4)=-817.6±43.8 kJ mol-1.

Abstract: The temperature-dependent heat capacity of vysotskite, PdS, has been determined for the first time by adiabatic, relaxation, and differential scanning calorimetry in a wide temperature range and standard thermodynamic functions of PdS have been calculated. The 298.15-K values thus obtained are [InlineEquation not available: see fulltext.] = 43.65 ± 0.09 J/(mol K), S° = 51.98 ± 0.10 J/(mol K), Н°(298.15 К) ? Н°(0) = 8.03 ± 0.02 kJ/mol, and Ф° = 25.03 ± 0.05 J/(mol K). Using the present results and data in the literature, we obtained ΔfH°(PdS, 298.15 K) = –74.0 ± 1.0 kJ/mol and ΔfG°(PdS, 298.15 K) = –68.7 ± 1.0 kJ/mol.

Direct electrical measurement of the conversion of metal acetates to metal sulfides by hydrogen sulfide

Copper acetate and related metal salt films react directly with hydrogen sulfide at room temperature to form metal sulfides, resulting in conductivity changes as large as 108. The observed changes in conductivity are related to the solubility p
Sulfurization-induced partially amorphous palladium sulfide nanosheets for highly efficient electrochemical hydrogen evolution

, p. 1368 - 1371 (2021)
A partially amorphous palladium sulfide was synthesized by sulfurizing crystalline palladium nanosheets facilely, which shows excellent activity and stability towards hydrogen evolution in alkaline media, even superior to the performance of the commercial Pt/C catalyst. The enhanced performance could be attributed to the amorphization transformation and the nanosheet morphology.
Studies of the reduction and reoxidation processes of Nd4PdO7
Andersson,Jansson,Nygren
, p. 83 - 89 (1998)
It has been demonstrated that Nd4PdO7, when exposed to a gas mixture of CO and He, fully decomposes to Nd2O3 and nano-sized Pd-particles, which are found on the surfaces of the micron-sized Nd2O3 particles. This material, known to exhibit catalytic activity for oxidation of CO and hydrocarbons, and reduction of NO, can be reoxidised to Nd4PdO7 by heat treatment at 1085°C in air for a short period of time, i.e. when utilised as catalyst this material can easily be regenerated if it has become aged. The reduced material has been studied in scanning and transmission electron microscopes (SEM and TEM) equipped with element analysis facilities, and characterised by X-ray powder diffraction (XRPD) studies. A wet-chemistry method for extraction of the nanoparticles formed has been developed, based on selective dissolution of Nd2O3, and the bare Pd-particles have been characterised by XRPD, SEM and TEM studies. The reduction and reoxidation of Nd4PdO7 material was monitored in a thermogravimetric setup. Nd4PdO7 decomposed in air to Nd2O3 and Pd at 1185°C, which is ≈50°C higher than the previously reported decomposition temperature.
Reinvestigation of the structure of PdS.
Brese,Squattrito,Ibers
, p. 1829 - 1830 (1985)
The crystal structure of synthetic PdS (vysotskite) is described with greater precision (cell dimensions a 6.429(2), c 6.611(2) A, space group P42/m, Z = 8). The square planar coordination of the Pd atoms is more regular than previously reported (M.A. 7-81) and is compared with that in braggite (M.A. 74-948).-J.E.C.

, p. 1722 - 1725 (2000)
The products of interaction of components in the donor-acceptor electron-transport (DAET) DMSO-HBr system and their complex formation with the metallic palladium surface were studied. H2O and Me2S (main reaction products) and CO, CS2, C2H6, MeBr, H, and CH4 (minor reaction products) were found in the gas phase by mass spectrometry (MS). The samples of metallic palladium treated with the DAET system with a components ratio corresponding to the minimum and maximum rates of metal dissolution were studied by the methods of thermoprogrammed desorption with MS detection (TPD-MS) and XPS. According to the TPD-MS data, two forms of Me2S are present on the metal surface, whereas the XPS method detected two complexes with the molecular compositions Pd11Br4S1.26 and Pd11Br3.86S1.42. The addition of an aqueous solution of NaOH to the system results in the formation of HCOONa, which indicates that compounds (CH2O, HCOOH) capable of reducing the palladium complexes are present in the DAET system.
