The Improved Covalent Coupling Induced by Bi Cations in CoBiSe_x Nanosheet Arrays for Stable Water Electrolysis

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: March 25, 2025

Transition metal selenides (TMSes) with high electrical conductivity, easily regulated morphological structure, and unique electronic structure have been explored as promising electrocatalysts for electrolytic water, while the lower intrinsic electrocatalytic capability has limited their wide application. Herein, we obtained CoSe nanosheet arrays Bi cations incorporation (CoBiSex arrays) driven by spinel oxides. Compared oxides, low electronegativity of Se in CoBiSex leads to a portion Co2+ spin states (t2g6eg1) due covalent interaction between Co Se, which can facilitate charge transfer. Density functional theory (DFT) calculation results further identify redistribution electron density from Co, intensifying adsorption OOH* during water process 140 h robust catalytic performance. This work offers strategy exploring TMSe materials potential applications process.
