A platinised TiO2 film with both photocatalytic and non-photocatalytic activities towards the oxidation of formic acid

摘要

A platinised Ti02/lTO film, Pt-Ti02/ITO, was prepared by a dip-coating and subsequent photodeposition procedure. Compared with bare Ti02/ITO film, Pt-Ti02/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 Ti02 was partly responsible for degradation of formic acid in the photocatalytic process. The non-photocatalytic activity of Pt-Ti02/ITO film is very dependent on its preparation method.
