摘要
采用提拉-光沉积两步法制得了一种新的铂化TiO2光催化薄膜,实验结果表明该光催化薄膜对甲酸的降解同时具有光催化和化学催化双重活性,因此,纳米Pt的化学催化作用可作为增强TiO2光催化氧化有机污染物效率的一种新的机理.
A platinised TiO2/ITO film, Pt-Tio2/ITO, was prepared by a dip-coating and subsequent photo-deposition procedure. The TiO2/ITO film not only possesses a relative high photocatalytic activity but also shows a rather chemical catalytic activity towards HCOOH degradation. It is considered that the chemical catalytic effect on the origin of the enhanced photocatalytic efficiency by platinising TiO2 for degrading organic pollutants is a new mechanism.
