摘　　要：Oxygen evolution reaction(OER)plays a key role in the electrochemical conversion and storage processes,but the sluggish kinetics of OER strongly impedes its large-scale applications.We herein reported the in situ growth of Fe-benzenedicarboxylate(Fe-BDC)on Co(OH)_(2) nanoplates[Fe-BDC/Co(OH)_(2)]that showed remarkably enhanced OER activity than the pristine Co(OH)_(2).The incorporation of Fe species could enhance the intrinsic OER activity of Co and BDC could increase the electrochemically active surface area(ECSA),thus resulting in dramatically enhanced OER activity.In situ Raman spectroscopy characterization disclosed that Fe-CoOOH reconstructed from Fe-BDC/Co(OH)_(2) was the real active site for OER.This work highlights the significance of rational tailoring of the nanostructure and electronic structure of Co(OH)_(2) and provides more opportunities for its widespread applications.
