Photocatalytic Splitting of Water Over a Novel Visible-Light-Response Photocatalyst Nd2InTaO7
Abstract
A new visible-light-response photocatalyst Nd2InTaO7 with pyrochlore-type structure crystallized in a cubic system with the space group Fd3m was synthesized by a solid-state reaction method. The H2 evolution was
obtained from Pt/CH3OH/H2O solution and pure H2O, and O2 evolution was generated from an aqueous AgNO3
solution under visible light irradiation (k[400 nm). The high photocatalytic performance of Nd2InTaO7 supported the existing view that the photocatalytic activity correlated with the lattice distortion.
