Visible light-induced photochemical oxygen evolution from water by 3,4,9,10-perylenetetracarboxylic dianhydride nanorods as an n-type organic semiconductor†
Abstract
3,4,9,10-Perylenetetracarboxylic dianhydride (PTCDA) nanorods as an n-type organic semiconductor are utilized to construct a powder-based photocatalytic water oxidation system with cobalt oxide as a cocatalyst, which achieved an apparent quantum efficiency of 4.6 ± 0.3% under visible light irradiation at 410 nm.
