Electrochemical production of “green” hydrogen powered by renewable energy resources is potentially promising technology enabling carbon neutrality with zero emission of carbon dioxide. The aim of this research is to (1) design electrocatalysts with excellent performance and durability and (2) develop energy-efficient alkaline water electrolyzers.

Power-to-X conversion is a sustainable technology that converts renewable electricity into chemicals, which provides versatile routes to synthesize valuable chemicals. The aim of this research is to (1) design a new electrolysis system with economic feasibility and (2) discover new electrochemical reactions that can replace energy-demanding chemical processes.

Solar-driven electrolysis promotes artificial photosynthesis to produce value-added chemicals with less electricity or without any bias. The aim of this research is to (1) fabricate highly efficient perovskite solar cells and (2) combine with electrolysis system for semi-artificial photosynthesis to synthesize e-chemicals and e-fuels.
