CeO₂-supported multi-nuclear Nb_xS_y clusters for hydrogen evolution reaction

Abstract

The possibility of CeO2 supported multi-nuclear NbxSy clusters for HER catalysis have been explored by DFT method. The CeO2 support not only could stabilize NbxSy clusters, but also acts as...

Promising Electrolyte Additive-Induced Multifunctional Alloy Interphase Enabling Stable Zinc Anodes for Aqueous Zinc-Ion Batteries

“…5 However, zinc anodes in aqueous electrolytes inevitably encounter zinc dendrite growth and inevitable side reactions, including hydrogen evolution reaction (HER), chemical corrosion, and continuous deposit of passivating byproduct Zn 4 SO 4 (OH) 6 •xH 2 O. 6,7 These problems deteriorate the zinc plating/stripping Coulombic efficiency (CE) and cycling stability of zinc-ion batteries. 8 Hence, strategies must be devised to enhance the reversibility and durability of zinc anodes to facilitate the largescale commercialization of AZIBs.…”
