D3.04 - Control of Surface/Interface Structures of Nano Metal/Semiconductors for Efficient Solar Chemical Conversion 
April 23, 2014   9:30am - 10:00am

Surface/interface structure of metal/semiconductor materials plays an important role in determining efficiency of photoelectrochemical and photocatalytic solar energy harvesting and storage. This talk will introduce the latest research activities in our group1-11), focusing on our challenges on the scientific and technological possibilities of nano-photocatalytic materials for solar chemical conversion. Efforts to explore suitable materials and to optimize their energy band configurations for specific applications, and the design and fabrication of advanced photocatalytic materials in the framework of nanotechnology will be introduced, taking examples of recent research progress on Ag3PO4 and other newly developed materials system. Specifically, design and control of surface/interface nano-structures of metal/semiconductors from both experimental and theoretical approaches for efficient solar energy harvesting will be introduced and discussed in detail.References[1] Z.
