Due to the volume expansion effect during charge and discharge processes, application of transition metal oxide anode materials in lithium-ion batteries is limited. Composite carbon coating are often considered feasible improvement methods. In this study, three types TiO
Density functional theory and the calculations of oxygen nucleophilicity have been applied to an analysis oxidative dehydrogenation (ODH) propane on (010) surface V2O5. These show that energetically preferred initial step is dissociative adsorption form i-propoxide hydroxyl species. Two VO groups [O(1)] bonded by a V−O−V bridge are required. One vanadyl attacks β-C atom converted V−OCH2(CH3)2 species, whereas other group into V−OH group. The activation barrier for this process 9.4 kcal/mol....
Constructing van der Waals heterojunctions with excellent properties has attracted considerable attention in the field of photocatalytic water splitting. In this study, four patterns, coined A, B, C, and D Janus Ga2SSe/Bi2O3 (vdW) different stacking modes, were investigated using first-principles calculations. Their stability, electronic structure, optical analyzed detail. Among these, patterns A C demonstrate stable behavior operate as direct Z-scheme photocatalysts, exhibiting band gaps...
In this study, a novel calcium phosphate/polyacrylamide copolymer/α-type hemihydrate gypsum (CPO/PAM/α-HHG) composite material was prepared by polymerising stable inorganic CPO precursor, end-capped with triethylamine (TEA), an organic polyacrylamide (PAM) hydrogel to form CPO/PAM precursor solution. Subsequently, solution mixed α-hemihydrate gypsum. The effects of addition and on the slurry flowability, initial setting time, mechanical properties hardened specimens CPO/PAM/α-HHG were...
Harnessing solar energy for photocatalytic water splitting and hydrogen fuel production necessitates the development of advanced photocatalysts with broad spectrum absorption efficient electron-hole separation. In this study, we systematically explore potential SGa2Se/TeMoS heterojunction as a water-splitting photocatalyst using first-principles calculations. Our results indicate that while exhibits type-II band alignment, its edge positions are inadequate initiating redox reactions. To...

Two-dimensional MX2 (M = Mo, W; X S, Se, Te) homo- and heterostructures have attracted extensive attention in electronics optoelectronics due to their unique structures properties. In this work, the layer-dependent electronic optical properties been studied by varying layer thickness stacking order. Based on quantum theory of atoms molecules, topological analyses interatomic interactions layered WX2/MoX2, including bond degree (BD), length (BL), angle (BA), detailed probe structure-property...
Owing to their low lattice thermal conductivity, many compounds of the n(PbTe)-m(Bi2Te3) homologous series have been reported in literature with thermoelectric (TE) properties that still need improvement. For this purpose, work, we implemented band engineering approach by applying biaxial tensile and compressive strains using density functional theory (DFT) on various series, namely Bi2Te3, PbBi2Te4, PbBi4Te7 Pb2Bi2Te5. All fully relaxed Pb2Bi2Te5 are narrow band-gap semiconductors. When...

Thermoelectric materials have attracted extensive attention because they can directly convert waste heat into electric energy. As a brand-new method of alloying, high-entropy alloys (HEAs) much in the fields science and engineering. Recent researches found that HEAs could be potentially good thermoelectric (TE) materials. In this study, special quasi-random structures (SQS) PbSnTeSe consisting 64 atoms been generated. The transport properties highest-entropy PbSnTeSe-optimized structure were...
