摘要
二氧化钛光催化剂的应用比其他半导体光催化剂更广泛,但它也有一定的局限性,因此需对二氧化钛的性能进行改进,可以拓宽二氧化钛的光响应范围,并提高光载体的形成、分离和转移效率,消除电子孔组成真空,提高半导体催化剂的光催化性能。着重介绍了提高二氧化钛作为半导体光催化剂的光催化活性的改性方法,包括金属及非金属的掺杂、包覆以及负载等,并对目前的研究成果以及遇到的问题进行了综述,最后就二氧化钛作为半导体光催化剂的未来发展前景进行了简单分析。
Titanium dioxide photocatalysts are used more widely than other semiconductor photocatalysts,but they also have certain limitations.Therefore,the performance of titanium dioxide needs to be improved,which can broaden the light response range of titanium dioxide,improve the formation,separation and transfer efficiency of light carriers,eliminate the vacuum of electronic pore composition,and improve the photocatalytic performance of semiconductor catalysts.The modification method to improve the photocatalytic activity of titanium dioxide as a semiconductor photocatalyst was introduced,including the doping,coating and loading of metals and non-metals,and the application,current research results and problems encountered were reviewed,and finally the future development prospects of titanium dioxide as a semiconductor photocatalyst were briefly analyzed.
