摘要

In this work, mulberry shaped TiO₂-Au nanocomposite has been successfully prepared by a one-step hydrothermal method relying on the redox reaction between Au (III) and Ti (III) with polyvinyl pyrrolidone (PVP) as protective agent for the first time. PVP plays an important role on monodisperse and homogeneity of mulberry shaped TiO₂-Au. The TiO₂-Au nanocomposite shows excellent stability towards the catalytic reduction of water under visible light. Based on characterization and testing, we propose the photocatalytic process for efficient H₂ generation. Uniformly dispersed Au NPs enhance visible light absorption on account of the LSPR, leading to the H₂ evolution increased.
