Research in the Wu group focuses on energy materials for photovoltaics, batteries and catalysis. We are interested in the thermodynamics and kinetics of the nanocrystal formation mechanism in order to achieve the composition, size and shape control. We are also interested in understanding and controlling the forces between nanoparticles for their assemble into ordered superstructures. Moreover, since the solid/liquid interface plays a critical role in dye-sensitized solar cells, batteries and catalysis, our research has an emphasis on the surface structure, electrochemistry and photoelectrochemistry of seminconducting nanomaterials in liquid electrolytes, such as the molecular structural configuration of dye adsorption on the oxide support, the electron transport dynamics in the oxide network and the band structures of new oxide anode materials.
