The Electrochemical Nanoengineering Group is part of the Mechanical Engineering Department at the University of Hong Kong. Our research focuses on the electrochemical fabrication of nanostructured materials and their applications in solar, thermal and electrochemical energy conversion and storage. Our research focuses on the electrochemical fabrication of nanostructured materials and their applications in the following research topics, which is interdisciplinary and combines mechanical engineering, chemical engineering, electrical engineering, and materials science.

• Thermo-electrochemical energy conversion: thermogalvanic cell (TGC), thermally regenerative electrochemical cycle (TREC), thermal capacitive electrochemical cycle (TCEC).
   

• Photo-electrochemical energy conversion: dye-sensitized solar cells (DSSCs) and perovskite solar cells (PSCs).
   

• Electrocatalyst: hydrogen evolution reaction (HER), oxidation reduction reaction (ORR), water splitting, formic acid dehydrogenation, CO2 conversion, and non-enzymatic glucose biosensor.
   

• Nanofluids: liquids containing suspensions of solid nanoparticles for the enhancement in heat transfer and their potential applications in energy technologies.
