摘要：

Spinel cobalt oxide (Co3O4), consisting of tetrahedral Co2+ (CoTd) and octahedral Co3+ (CoOh), is considered as promising earth-abundant electrocatalyst for chlorine evolution reaction (CER). Identifying the catalytic contribution of geometric Co site in the electrocatalytic CER plays a pivotal role to precisely modulate electronic configuration of active Co sites to boost CER. Herein, combining density functional theory calculations and experiment results assisted with operando analysis, we found that the CoOh site acts as the main active site for CER in spinel Co3O4, which shows better Cl- a...
