Abstract
A platinised TiO 2/ITO film, Pt-TiO 2/ITO, was prepared by a dip-coating and subsequent photodeposition procedure. Compared with bare TiO 2/ITO film, Pt-TiO 2/ITO film not only possesses a relative high photocatalytic activity but also shows a rather non-photocatalytic activity towards HCOOH degradation at room temperature and atmosphere pressure. The non-photocatalytic effect of platinised TiO 2 was partly responsible for degradation of formic acid in the photocatalytic process. The non-photocatalytic activity of Pt-TiO 2/ITO film is very dependent on its preparation method.
