After hybridized with graphene, the photocatalytic performances of gamma-Bi2MoO6 were increased about 2-4 times. The photocatalytic activity enhancements were dependent on the amount of graphene and it was found that the optimal hybridized amount of graphene was about 1.0 wt%, which was close to the monolayer disperse of graphene on gamma-Bi2MoO6 surface. The mechanism on the enhancement of photocatalytic activity is attributed to the higher separation efficiency of photo-induced electrons and holes, which come from the electronic interaction between gamma-Bi2MoO6 and graphene. The electronic interaction was verified by the photoelectrochemical measurements. (C) 2011 Elsevier B.V. All rights reserved.
