(Photo)electrocatalytic electrode materials for clean energy technologies
Our group is currently developing functional low-dimension metallic and semiconductor electrode materials with synergistic functions for sunlight harvesting, conversion, and storage into chemical fuels. Research in this area emphasizes the unique catalytic and photonic properties of nanostructured electrode materials to enhance the efficiency and selectivity of the solar-to-fuel conversion. Advanced electrochemistry and spectroscopy techniques are frequently used in our research to study the structure-function relationships and surface chemistry of these materials.
