Photoanodes: Vastly Enhanced BiVO4 Photocatalytic OER Performance by NiCoO2 as Cocatalyst (Adv. Mater. Interfaces 19/2017)

In article number 1700540, Peng Wang and co-workers report that bismuth vanadate (BiVO4), when assisted by nickel cobalt oxides (NiCoO2), shows vastly improved photo(electro)catalysis (PEC) oxygen evolution reaction (OER) performance. The role of NiCoO2 is two folds: OER cocatalyst and band structure adjustment. The dual-role on single-component NiCoO2 improves surface reaction kinetics for PEC OER and enhances charge separation on the surface BiVO4 simultaneously, which is the determining factor for the unprecedented performance.
