Abstract

A versatile synthetic method, which is based on a low-temperature hydrothermal technique, is developed for the fabrication of a microporous ZnO/TiO₂ composite catalyst with different structures (e.g., amorphous, amorphous/crystalline and crystalline). In particular, a novel microporous ZnO/TiO₂ composite with amorphous/crystalline structure is obtained with a 3/1 M ratio of Ti/Zn. This novel ZnO/TiO₂ composite heterostructure not only has a large specific surface area (311.9 m² g^-1) but also exhibits outstanding performance during solar water splitting reactions to generate hydrogen without a noble metal co-catalyst. Based on our in-depth mechanistic analysis, the synergistic effect between the amorphous ZnO and crystalline TiO₂ is responsible for the enhanced performance of this material.
