Research Interests
Our group mainly focus on the nano materials preparation and application in the cleaning energy, environmental therapy and bio-related applications.
1.Solar energy conversion
- Solar Fuel Generation.
Solar energy, as an aboundant energy source, is still under exploitation. Recently solar power has been developed and made a great progress. Solar hydrogen generation is another important way to utlize solar energy. TiO2, as a wide band gap semiconductor, is extensively employed in the energy harvest, conversion and storage due to its good electron transfer capability. However, the big problem of TiO2 is hard to absorb visible light due to it large band gap. Enhanced visible light response photocatalyst is an important issue for solar hydrogen generation. - Solar power generation.
2. Enviroment therapy and self-cleaning coating
Facing serious air and water pollution in China, photocatalytic decompose organic waste in air and water is another project in our group. Semiconductor photocatalyst can use for not only H2production, also organic degradation. We also investigate the degradation of organic molecules with these photocatalysts. And making thin film photocatalytst coating as self-cleaning coating.

3. Fluorescent graphene quantum dots
Carbon nanomaterials have attracted more and more attention, like C60, Carbon nanutube, Graphene, which exhibit execellent photonic and electronic properties. When graphene was cuted into nanosize and passivated with amine, graphene quantum dots exhibit high luminescent properties. Our group developed a simple method and prepared graphene quantum dots with high quantum yield emission through bottom-up route. We used these fluorescent graphene quantum dots as an imaging agent and combine therpay agent to form a theranostic agent.
