A CoOx-modified SnNb2O6 photoelectrode for highly efficient oxygen evolution from water†
Abstract
SnNb2O6 has arisen as a candidate for photoanodes for solar water splitting. CoOx cocatalyst-loaded SnNb2O6 showed a stable, high anodic photocurrent with an incident photon-to-current conversion efficiency (IPCE) of 18% at 0.6 VRHE and a half-cell solar-to-hydrogen (HC-STH) efficiency of 0.39% at 0.6 VRHE.
