In situ fabrication of AgVO 3 /BiVO 4 graphene aerogels with enhanced photocatalytic activity

Ying Wang, Maoli Chen, Qin Xie, Bolin Wang, Li Lin, Yuanyuan Jiang, Li Zhang, Ying Zhao, Yunsong Zhang, Maojun Zhao A 3D porous AgVO3/BiVO4@GA was fabricated by an in situ ion exchange method. In the as-prepared AgVO3/BiVO4@GA photocatalyst, GA with a 3D macrostructure, porous channels and excellent electrical conductivity can efficiently support AgVO3 and facilitate cyclic regeneration, improve the mass transfer of reactants/products and promote the photogenerated charge separation rate in the photocatalytic process. Furthermore, benefitting from the ion exchange between Ag+ and Bi3+, the BiVO4 can be well dispersed on AgVO3, which avoids the agglomeration of AgVO3 and BiVO4 and further enhances the photocatalytic performance and cyclic stability of AgVO3/BiVO4@GA.
