Anchoring CoO Domains on CoSe2Nanobelts as Bifunctional Electrocatalysts for Overall Water Splitting in Neutral Media.
A facile in situ partial surface-oxidation strategy to integrate CoO domains with CoSe2nanobelts on Ti mesh(denoted as CoO/CoSe2) via direct calcination of CoSe2-diethylenetriamine precursors is reported. The resulted self-supported CoO/CoSe2exhibits an outstanding activity and stability in neutral media toward both hydrogen evolution reaction and oxygen evolution reaction.
