共掺杂改性TiO2光催化材料的研究进展

以光催化材料TiO_2为研究对象,从金属、非金属之闻的共掺杂出发,介绍了近些年来TiO_2光催化剂与双金属、双非金属、金属与非金属共掺杂的研究现状。发现,当对TiO_2进行双元素的共掺杂,且掺入的两种元素选择适当,掺入量合适时,能够进一步提高光催化材料TiO_2的光催化性能,指出其制备方法的多样化及其逐渐完善,将是其发展方向。

Development of the co - doping photocatalysis material TiO2

This article set the photocatalytic material-TiO_2 for the study object.The recent progress of co- doping of TiO_2 photocatalyst with double metal and double non-metal,metal and non-metal were introduced. The results showed that when two appropriate elements are chosen and the doping concentrations and co-doping proportions are optimal,the photocatalytic activity could be enhanced.Diversity and promotion of the preparation methods would be the development trends.
