摘要

研究了B, F, S梯度掺杂TiO₂薄膜的光催化活性，考察了晶相结构及吸收光波长的变化. 结果表明，离子单掺杂或共掺杂后TiO₂薄膜的光催化活性均优于表面掺杂的TiO₂薄膜，共掺杂TiO₂薄膜的光催化性能优于单掺杂的TiO₂薄膜，离子三掺TiO₂薄膜对品红的最佳降解率可达81.11%，与离子间的协同效应有关.

Abstract

Photocatalytic activities of B, F and S gradient doped TiO₂ thin films were studied. The microstructure and optical property were characterized. The results showed that the B-F-S doped TiO₂ thin film using gradient doping method exhibited much higher photodecomposition activities than using surface doping process. The best degradation rate of magenta by three ion doped can reached 81.11%, which was due to the synergistic effect between B, F and S ions.

Key words： TiO2 films; F?B?S doped; sol?gel method; gradient doping; photocatalyst
