摘要

Ag3VO4/β-AgVO3 nanocomposites were successfully fabricated by chemical precipitation and hydrothermal method. The composites displayed excellent photocatalytic activity in comparision with those of pure β-AgVO3 and Ag3VO4, which may be primarily ascribed to the matched energy structures. The sample with a molar ratio of 30% Ag3VO4 to β-AgVO3 showed the highest photocatalytic activity for RhB degradation, which was almost 9 and 2.4 times higher than those of pure β-AgVO3 and Ag3VO4, respectively. In addition, the trapping experiments also confirmed that holes and hydroxyl radicals are the active species for RhB degradation, and the possible mechanism for enhanced photocatalytic activity was proposed.
