A new visible-light-driven photocatalyst Na0.5Bi1.5VMoO8 was developed by making a solid solution of BiVO4 and (NaBi)(0.5)MoO4. The prepared powders were confirmed crystallizing in the tetragonal scheelite crystal structure by the XRD patterns and Raman spectra. Different from that of the tetragonal BiVO4, Na0.5Bi1.5VMoO8 showed a high activity for photocatalytic 02 evolution under visible light irradiation, which is even better than that of monoclinic BiVO4, a well-known efficient visible-light-driven photocatalyst. The mechanism of the improved activity of Na0.5Bi1.5VMoO8 was discussed. (c) 2007 Elsevier B.V. All rights reserved.
