摘要
以甲醛的光催化氧化反应为指标反应 ,对商品二氧化钛的光催化性能进行了对比研究 ,发现不同的商品二氧化钛 ,其光催化活性呈现较大的差异 .利用XPS ,XRD等手段研究了各种二氧化钛的表面物种和晶体结构 .
The photocatalytic Oxidation of HCHO was used as a model reaction to investigate the photocatalytic properties of different commercial TiO 2 catalysts. Parallel experiments have been performed with a black_light lamp in a close photoreactor in laboratory.Different photocatalyst activities were observed. The results showed that Degussa P25 presented a higher activity for HCHO disapperance than the other commercial catalysts because of its greater surface area and crystal structure. The factors that influence photocatalytic activity of the catalysts were discussed.
