摘要/Abstract

摘要： 以工业有机颜料C.I.颜料黄154（PY154）为敏化剂，采用溶剂热法制备了不同PY154含量的TiO₂光催化剂（PY154-TiO₂），并对其进行了表征。以可见光下对罗丹明B（RhB）的降解率为模型，考察了PY154-TiO₂的光催化性能。结果表明，TiO₂与PY154复合后，光响应范围由紫外区拓展到可见光区，其光催化活性明显高于TiO₂。最后对催化剂的稳定性进行了研究，重复使用5次后其活性没有明显降低，说明PY154-TiO₂具有较好的稳定性。

Abstract: Using organic pigment Yellow 154 as sensibilizer, TiO₂ photocatalyst(PY154-RiO₂) with different PY154 contents has been prepared by solvothermal method, and the photocatalysis capacity is characterized. The photocatalysis capacity of PY154-TiO₂ is evaluated under visible light irradiation, taking the degradation rate of Rhodamine B as model reaction. The results indicate that after TiO₂ has combined with PY154, the photoresponse range extends from UV to visible light region, and its photocatalysis activity is significantly higher than TiO₂. At the end, the stability of the catalyst is studied, and it is found that its activity is not significantly reduced after being used 5 times repeatedly, which demonstrates that it has excellent stability and recyclability factors.

Key words: sensitizer, solvothermal method, Rhodamine B, photocatalytic activity
