Our research mission is to develop new classes of nanostructures for novel electrochemical energy storage and conversion devices and techniques , with an emphasis on understanding the fundamental issues of structural assembly and growth that will enable the rational control of material composition, nanostructure, property and functionality, mainly involving:
1. How to Reduce CO2 Emissions from the Source:
....1) Solid Oxide Fuel Cell (SOFC): Hydrogen and hydrocarbon-fueled oxide-ion conducting SOFC, and alkane dehydrogenation to alkene in proton-conducting SOFC.
.....2) Electrochemically Extracting Resources from Seawater: Developing new nanomaterials to electrochemically extracting uranium species from seawater.
2. How to Convert Existing CO2 to High-Value Fuels and/or Chemicals:
....1) Room Temperature Electrochemical CO2 Redution Reaction (CO2RR): Aiming to reach the ultimate goal of mitigating greenhouse effect via synthesizing specific nanostructures with controllable sizes, morphologies and compositions as efficient catalysts for CO2RR to fuels, and establish and understand the size, composition and structure-activity relationship and especially, the underlying mechanisms.
....2) High Temperature Electrochemical CO2 Redution Reaction (CO2RR): Developing efficient catalysts in the form of perovskite oxides with in situ exsolved metal/bimetal nanoparticles for CO2/H2O electrolysis, CO2 and H2O co-electrolysis, and other CO2-involved electrocatalysis.
3. Other Energy Conversion and Storage Related Devices and Techniques: Including oxygen evolution reaction (OER), oxygen reduction reaction (ORR), hydrogen evolution reaction (HER) and other energy conversion and storage related devices and techniques.
