Abstract

A novel microporous ZnO/TiO2 heterostructure, which consists of crystalline TiO2 decorated with amorphous ZnO, have been fabricated by a facile one-step synthetic methods. The results showed that the phase composition of the growing units and the intrinsic crystal structure are seriously controlled by the synthetic environment. Particularly, we have successfully captured the transformation process of the amorphous/crystalline heterostructure by adjusting the pH value. The sample with high pH value (8~12) is favorable to the formation of an amorphous/crystalline composite structure. This study demonstrates that by properly choosing the synthesis parameters, it is possible to fine-tune the microscopic and macroscopic properties of the semiconductor heterostructure. It is hoped that this work can draw attention to making better use of amorphous to synthesize more ef cient amorphous-based nanocomposite photocatalysts for H2 generation from water splitting.
