SKKU Team Develops Non-Precious Catalyst for Green Hydrogen Production
A research team from SKKU and Kyungpook National University has created a non-precious metal catalyst for water electrolysis, enhancing hydrogen production efficiency. This innovation addresses the slow oxygen evolution reaction, traditionally reliant on costly precious metals, by utilizing lattice oxygen through precise atomic bond control.

A joint research initiative led by professors from Sungkyunkwan University and Kyungpook National University has produced a highly efficient, non-precious metal catalyst for water electrolysis. The team employed a top-down materials design strategy, fracturing cobalt oxide into nanoclusters under 2 nm while optimizing atomic bond length to 2.03 Å, allowing lattice oxygen to actively participate in reactions.
This catalyst shows superior performance compared to iridium-based systems, sustaining over 100 hours of operation under high-current conditions. The findings, published in Applied Catalysis B, could significantly lower production costs and accelerate commercialization of eco-friendly energy technologies.
