[RESEARCH INTEREST I] - WATER ELECTROLYSIS
[RESEARCH INTEREST I] - WATER ELECTROLYSIS
We aim to develop robust and scalable electrochemical systems for water electrolysis using sustainable oxide-based catalysts. Focusing on alkaline and seawater environments, our research leverages metal oxides to promote efficient oxygen and hydrogen evolution reactions. Through interfacial electrochemistry, we address key challenges under high-potential conditions—such as suppressing active chlorine formation and preventing catalyst degradation—to enhance long-term stability. We aim to reach industrial-level current densities while ensuring long-term material stability and reaction selectivity.

[RESEARCH INTEREST II] - CO2 CONVERSION
[RESEARCH INTEREST II] - CO2 CONVERSION
We aim to develop an electrochemical CO₂ conversion platform that integrates both direct and indirect pathways, with a central focus on indirect systems. Our approach utilizes a uniquely designed metal–CO₂ configuration—pioneered in our group—which captures CO₂ through pH-driven dissolution processes under electrochemical operation. This method not only allows for efficient CO₂ capture without external absorbents, but also enables its subsequent conversion into valuable products such as hydrogen and carbon-based fuels. Furthermore, by employing seawater as a reactive medium, the system can be extended to promote mineralization of valuable ions (Mg²⁺;Ca²⁺;Sr²⁺;Li⁺), contributing to carbon utilization and environmental sustainability.

[RESEARCH INTEREST III] - ELECTROSYNTHESIS
[RESEARCH INTEREST III] - ELECTROSYNTHESIS
We aim to develop integrated electrocatalytic systems for the sustainable synthesis of hydrogen, hydrogen peroxide, and ammonia—key chemicals for future energy and industry. To improve energy efficiency and product selectivity, our research focuses on alternative anodic reactions that replace the conventional oxygen evolution reaction. These include the electrochemical oxidation of biomass-derived organic acids, Kolbe electrolysis for the formation of long-chain hydrocarbons, and the oxidative upcycling of waste organics such as plastics. By combining tailored catalyst design with controlled reaction environments, we seek to co-produce valuable fuels and chemicals while advancing circular electrochemical technologies based on renewable and waste-derived feedstocks.

[RESEARCH INTEREST IV] - SEMICONDUCTING MATERIALS
[RESEARCH INTEREST IV] - SEMICONDUCTING MATERIALS
We investigate the catalytic behavior of semiconducting oxides with a focus on electronic structure–property relationships. In particular, our group is pioneering the use of the Fermi level as a predictive descriptor for catalytic activity in degenerate semiconductors - start to behave like a metal, where high dopant concentrations significantly alter electronic states. We have demonstrated that this approach enables the selective promotion of desired reaction pathways while suppressing competing side reactions, offering a powerful tool for rational catalyst design. By moving beyond conventional surface-oriented models, we aim to establish electronic-structure-driven strategies for next-generation electrocatalysts for highly selective electrosynthesis platform.
