d10 or d0? Theoretical and experimental comparison between rutile GeO2 and TiO2 for photocatalytic water splitting†
Abstract
Rutile GeO2 with d10 metal in octahedral coordination possesses both a high charge separation rate and carrier mobility because the partial charge density is dominated by Ge–O anti-bonding for CBM. GeO2 is capable of photocatalytic water splitting, even visible light water splitting through combination with the sensitizer melon.
