摘要
以二氧化钛为代表的传统光催化材料只能利用短波长的紫外光,太阳光利用率和量子效率低,其广泛应用受到极大限制.针对这一问题,近年来我们开展了一系列具有高活性和(或)宽光谱响应(包括紫外及可见光)的新型纳米光催化材料的研究.本文简要总结了相应工作的进展,并对可能影响光催化材料的活性和光谱响应的相关因素进行了探讨.
The traditional photocatalysts, represented by TiO2, can only utilize ultraviolet light. The low solar energy utilization and low quantum efficiency of the photocatalysts seriously limit their wide applications. In recent years, we have carried out a series of studies on the novel nano-sized photocatalysts with high photocatalytic activity and/or wide spectrum response (including ultraviolet and visible light). In this paper, the research progress of the related topics was briefly summarized, and the possible influencing factors of photocatalytic activity and spectral response of photocatalyst were discussed.
