Photocatalysis and Photo (electro) catalysis

We are developing nanostructured materials for solar driven water splitting, CO2 reduction and N2 fixation, and organic compound conversion. We are especially interested in the design and fabrication of plasmonic nanostructures for photocatalysis and photoelectrochemical cells. We try to understand the charge dynamics, optimize the optical properties, and improve the interfacial catalytic activity for better performance. The plasmonic nanostructured materials include transition metals and noble metals, as well as semiconductors, which will be employed for the generation of clean fuels and environments remedy.

Surface plasmon resonance in biosensors

The development of nanotechnology is highly involved in biosensors, environmental protection. We are studying the SPR properties of metallic nanostructures and transition metal based plasmonic semiconductors. They are capable of sensing biomolcules as SPR systems. The in-situ detection based on the SPR systems would be used in artificial intelligence. We are working on the development of SERS  based lateral flow assay for point of care testing.

Near Infrared light photodetectors

Plasmonic semiconducting materials are unique optical properties. They have broad and strong absorption in visible and near infrared light range. The feasible tunability of LSPR modes of plasmonic semiconductors is useful for the development of photodetectors with high sensitivity.
