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.
