Ta3N5 as a Novel Visible Light-Driven Photocatalyst (λ<600 nm)

Abstract

Abstract A transition metal nitride, Ta3N5, is a novel photocatalyst responding to visible light. Ta3N5 evolves H2 and O2 by visible light (λ<600 nm) irradiation in the presence of sacrificial electron donor and acceptor, respectively without any noticeable photo-anodic or cathodic corrosion, representing a candidate for overall water splitting by visible light.
