Synthesis of High Entropy and Entropy-Stabilized Metal Sulfides and Their Evaluation as Hydrogen Evolution Electrocatalysts

“…From the pXRD analysis of the ME four- and HE five-metal sulfides (Figure ), it is clear that there are two distinct phases present in these systems: cubic sphalerite and hexagonal wurtzite. For bulk sphalerite and wurtzite, sphalerite is marginally more stable in atmospheric pressure and room temperatures, with a free energy difference of ∼10 kJ mol –1 . However, the entropy of wurtzite is ∼10 J mol –1 K –1 higher than that of sphalerite.…”

On the Rate of Interaction of Sodium Borohydride with Platinum (IV) Chloride Complexes in Alkaline Media

“…Taking into account the reaction of Pt(II) with oxygen in the form: where k 5 denotes the rate constant in Equation (22), all thermodynamic parameters for this reaction are known [ 33 ], and ΔG° (calculated with the Outotec HSC 7 Chemistry software) of this reaction is equal to –192 kJ at 298 K. As it can be seen, this reaction should be spontaneous, and it can be treated as irreversible. One can assume, that reaction (21) exhibits a negative value of ΔG°, and it has to also be spontaneous.…”

Ternary System CsI–PbI2–BiI3 and Thermodynamic Stability of Cesium Metal Halide Perovskites

“…The standard enthalpy of formation and entropy of BiI 3 (s) are taken from Cubicciotti . The heat capacity for the solid phase and enthalpy of melting are taken from Barin et al The heat capacity for BiI 3 (l) is taken from Cubiccioti and Eding . The enthalpy of formation of δ-CsPbI 3 is based on the measurements of Wang et al and Tsvetkov et al , The standard enthalpy of formation and entropy of α-CsPbI 3 are correlated to those of δ-CsPbI 3 via the enthalpy of the phase transition, as measured by Dastidar et al and Wang et al The standard entropy of δ-CsPbI 3 was optimized in this work, as well as the standard enthalpy of formation and entropy of Cs 4 PbI 6 and Cs 3 Bi 2 I 9 .…”
