Ta3N5 as a novel visible light-driven photocatalyst (lambda < 600 nm)
A transition metal nitride, Ta3N5, is a novel photocatalyst responding to visible light. Ta3N5 evolves H-2 and O-2 by visible light (alpha < 600nm) 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.
