Abstract

Abstract:

Gd/S co-doped TiO₂ photocatalysts have been prepared with Ti(OC₄H₉)₄, GdNO₃, H₂NCSNH₂ as raw mate- rials by sol-gel method. The experimental results show that a small amount of Gd doping can improve the photo-cata- lysis effect of TiO₂, but excessive Gd doping will inhibit the photo-catalysis effect. When the calcination temperature is 650 ℃, and gadolinium and sulfur doping ratios are 0.2% and 1%, respectively, the TiO₂ photocatalysts have the best effect, and its light response range expands significantly. X-ray diffraction characterization shows that Gd/S co-doped TiO₂ has the highest photocatalytic capacity when TiO₂ anatase crystal formation is doped with a small amount of rutile

Key words: doped TiO₂, sol-gel, photo-catalysis

摘要：

以钛酸四正丁酯、硝酸钆、硫脲为原料, 采用溶胶-凝胶法制备了Gd、S掺杂TiO₂光催化剂。实验结果表明:少量Gd的掺杂能提高TiO₂的光催化效率, 掺杂过多Gd对光催化剂有抑制作用。当煅烧温度为650 ℃, 钆、硫的掺杂比分别为0.2%、1.0%时, TiO₂光催化剂效果最好, 而且其光响应范围也明显拓展。XRD表征表明, 当TiO₂锐钛矿晶型中掺杂少量金红石相时, Gd、S共掺杂TiO₂光催化性能最好。
