Explore novel photocatalysts with narrow bandgaps

Activation of narrow-bandgap photocatalysts holds key to applicable solar fuel production. Our aim is to employ various strategies, such as VB control and doping to improve the photonic efficiencies of photocatalytic systems.

Design novel photocatalytic devices

The development of high-performance and scalable solar-driven artificial photosynthetic systems is a central issue for mass production of solar fuels. We design and develop novel devices, exemplified by photocatalyst sheets, to achieve efficient photocatalytic solar fuel production.

Develop hybrid systems for selective CO2 reduction

The development of sustainable CO2-to-fuel conversion systems is a central issue in closing the global carbon cycle and producing renewable chemicals and fuels from the greenhouse gas CO2. Our work explores novel approaches, for example, integrating a selective molecular catalyst on photocatalyst sheet, to increase the product selectivity of CO2 reduction reaction.
