Our lab is focused on developing advanced electrode materials to enable efficient and cost-effective hydrogen production in alkaline water electrolysis systems, with a research goal of improving the catalytic activity and stability of the electrodes as critical factors for enhanced performance and durability of the system.

We rigorously test the electrochemical performance of the developed materials to advance the technology of alkaline water electrolysis and contribute to the development of green hydrogen as a clean energy carrier.

Research efforts are underway to replace platinum with nickel as a catalyst in the hydrogen evolution reaction (HER) for efficient and cost-effective hydrogen production. Nickel has been shown to be a promising alternative to platinum based on the volcano plot evaluation of metal catalysts.

Efficient and stable oxygen evolution reaction (OER) catalysts are crucial for the commercialization of alkaline water electrolysis systems. While precious metal-based OER catalysts like IrO2 and RuO2 are commonly used, their high cost and scarcity limit their practical application.

Non-precious metal-based catalysts such as transition metal oxides (NiFeOx, CoFeOx, and MnOx) have shown promising OER performance and are being extensively researched for their potential as alternatives to precious metal-based catalysts.
