BiVO₄光触媒の光腐食メカニズムとZスキーム水分解への影響
Mechanism and Impact of BiVO₄ Photocorrosion in Z-Scheme Water Splitting Systems
Abstract:
Bismuth vanadate (BiVO₄) photoanodes suffer photocorrosion under illumination, dissolving vanadium and forming bismuth oxide. This instability hinders overall water splitting in Z-scheme systems (e.g. BiVO₄/SrTiO₃:Rh). We compare BiVO₄’s photocorrosion with WO₃’s greater stability, and review strategies—cocatalysts, protective layers, and junct…
