Research Topics

1. Fuel Cell Catalysis and ORR

Our research explores advanced electrocatalysts for the oxygen reduction reaction (ORR), ranging from platinum-supported systems to cost-effective alternatives. Recent efforts include the development of Pt–M core–shell alloys (PtNi, PtCo, PtIr), dealloyed PtCo integrated with graphene, and ultra-small Pt nanoparticles confined in single-walled carbon nanotubes (SWCNTs). In addition, bimetallic and ruthenium-based catalysts are designed to enhance activity for both ORR and OER.

2. Two-Dimensional Materials and Topological Structures

We focus on functional 2D materials such as MoS₂ and related transition metal dichalcogenides, along with graphite-based electrodes for next-generation lithium-ion batteries. Research also includes bimetallic MOFs and novel topological nanostructures engineered for multifunctional catalysis, hydrogen evolution, and energy storage.

3. Electrocatalysis and Solar-Driven Water Splitting

Our group investigates catalysts for green hydrogen production through water splitting, emphasizing bimetallic and core–shell systems for HER/OER. We also design photocatalysts for pollutant degradation and solar-to-chemical energy conversion.

4. Biomass Conversion and Sustainable Catalysis

Catalytic routes are being developed for transforming biomass-derived molecules such as fructose into high-value chemicals including 5-HMF and FDCA. Metal–organic frameworks (MOFs) and Pt@MOF hybrids are employed to achieve high selectivity in oxidation reactions.

5. Data-Driven Materials Discovery

Machine learning and data science tools are integrated into catalyst design and battery optimization. Materials informatics approaches are applied to analyze structure–property correlations and accelerate the discovery of high-performance materials.
