Abstract
Semiconductor photocatalysts have recently received great interests owing to their wide applications in environmental purification, solar energy conversion, and water splitting. However, enhancing the photocatalytic efficiency of TiO2 to meet the practical application requirements is still a challenge because of the bottleneck of the poor quantum yield caused by the rapid recombination of photogenerated electrons and holes. Much effort has been made to increase the electron-hole pair separation efficiency. Here, A novel ZnO/TiO2 amorphous/crystalline composite catalyst has been prepared by a low-temperature hydrothermal method. Based on the XRD and HRTEM analysis, there are amounts of anatase surrounded by amorphous ZnO when the mole ratio of Zn to Ti is 1/3, which could help improve the photocatalytic activity of the ZnO/TiO2 amorphous/crystalline composite catalyst. These encouraging nding could be expanded to other system or reactions and could open up a new direction in catalysis.
