Photocatalytic hydrogen production has great application potentials for the development and use of renewable energy resources. However, its widely practical application is still restricted by short lifetime and poor light utilization and of photocatalysts. This project aims to study on developing high-efficiency powder photocatalysts and photocatalytic reactor, and thus construct advanced photocatalytic device for hydrogen production.

Develop high-efficiency powder photocatalysts based on the interface design and defect-engineering (Figure 1): (a) synthesis of high quality graphene materials with tunable electronic structure from small molecular without catalysts, solvent and substrates. Metal nanoparticles and semiconductor supports are integrated to form efficient photocatalysts for hydrogen production; (b) The structure and property of metal oxides can be modified by constructing electron-rich defects properly, and thus resulting enhanced photocatalytic performance. Metal oxides with stable defects and outstanding photocatalytic performance are developed through modifying the defect nature.

Design the new kind of photocatalytic reactor to reduce the light path and light adsorption by solution (Figure 2). Improvement of light utilization and hydrogen production efficiency through multiple reflection of incident light. To setup a rotating disk photocatalytic system bring triple utilizations of hydrogen production, electricity generation and wastewater purification, maximizing the light utilization efficiency.
