Abstract:

The development of the composite photocatalytic materials with the heterojunction,including preparation methods of the heterogeneous composite materials, influence of the heterojunction on the catalytic activity and its application are analyzed. The presence of the heterojunction is an effective means to promote photocatalytic activity by increasing the separation efficiency of electron -hole separation. The new direction about the composite photocatalytic materials with the heterojunction is also proposed.
