Research Outline
My research focuses on developing transition-metal molecular catalysts for artificial photosynthesis and sustainable energy conversion with particular emphasis on CO2 reduction. By combining ligand design, spectroscopic analysis, electrochemical measurements, and theoretical calculations, I investigate the mechanisms of light-driven and electrochemical catalytic reactions. These studies aim to establish efficient and selective catalytic systems for converting CO2 into useful fuels and chemicals.
