Development in extending spectral response of photocatalytic materials

Photocatalysis has drawn much attention during past decades due to the potential applications in solving the current energy and environment crisis.The spectral response in wide range and high quantum efficiency are crucial to realize solar energy efficient conversion for photocatalytic materials.In the present work, we review briefly the recent progress of photocatalytic materials in responding to the UV, visible and near-infrared light.Some strategies to extend light response range and enhance the separation of charge carriers are illustrated.And challenges and prospects for further development in this field are presented.
