The Stability

Pt/K2La2Ti3O10 was prepared by impregnating K2La2Ti3O10 into H2PtCl6 solution. The structure of the photocatalyst was studied by means of XRD, UV-Vis spectroscopy and XPS. And the photocatalytic activities of the samples were examined in a Pyrex reaction cell by splitting methanol solution. The result revealed that Pt/K2La2Ti3O10 photocatalyst showed much higher activity than pure K2La2Ti3O10 and kept a high photocatalytic activity even after 120 hours of illumination. XPS showed that the valence state of Pt was reduced from Ptto Pt0 during the illumination.
