Research Progress in The Preparation and Application of TS-1 Photocatalysts

钛硅分子筛(TS-1)因具有优异的吸附能力、高选择性的催化活性中心和良好的稳定性而成为一类具有应用潜力的光催化材料。然而,其活性仍受限于电荷分离较低和光吸收不足。在众多光催化剂改性方法中,构建异质光催化体系具有简单可行、形式多样和性能突出等优点,在能源环境方面具有广阔的应用前景。本文总结了TS-1的制备方法、提出了与碳材料偶联、金属/非金属掺杂、贵金属负载和与半导体异质复合4种策略来TS-1光催化活性,分析了TS-1异质光催化剂在水分解制氢、CO 2还原和污染物的降解应用方面的研究现状。

Titanosilicon molecular sieve(TS-1)has become a kind of photocatalytic materials with potential application due to its excellent adsorption capacity,high selectivity of catalytic active center and good stability.However,its activity is still limited by low charge separation and insufficient light absorption.Among many photocatalyst modification methods,the construction of heterogeneous photocatalytic system has the advantages of simplicity,feasibility,variety of forms,and outstanding performance,which has broad application prospects in energy and environment.In this paper,the construction methods of TS-1,improve the photocatalytic activity of TS-1 four strategies of coupling with carbon material,meta or nonmetal doping,loading noble metal and heterogeneous recombination with semiconductor,and the application of TS-1 heterogeneous photocatalyst in the water splitting for hydrogen production,CO 2 reduction and degradation of pollutants are reviewed.
