摘要：

Photocatalyst, lead sulfide (PbS)-intercalated layer perovskite-type compound (K2La2Ti3O10), was synthesized via ion-exchange reaction, butylamine pillaring and sulfuration processes under the assistance of the microwave irradiation. The structure of the photocatalysts was determined by means of powder X-ray diffraction, scanning electron microscope, ultraviolet-visible diffuse reflection spectra and photoluminescence measurement. And the photocatalytic activity of the composite compound for hydrogen production was also investigated. The experimental results showed that the intercalation of PbS in the layered space of K2La2Ti3O10 greatly improved the absorption edge and the photocatalytic activity. Hydrogen production of the PbS-K2La2Ti3O10 was 127.19 mmol/(g cat) after 3 h irradiation of ultraviolet light. (C) 2012. Chinese Materials Research Society. Production and hosting by Elsevier Ltd.
