Electrochemical water splitting (Layered (hydr)oxide, perovskite)

Water electrolysis is considered one of the most promising methods to produce hydrogen due to various advantages including abundant resources, no greenhouse gas emission, and high efficiency. Also, water electrolysis helps mitigate the intermittent issues of renewable energies (e.g. solar, wind, geothermal), by storing the electricity in the form of chemical energy. 

We are designing new oxygen evolution catalysts using non-noble metal elements (e.g. transition metal (hydr)oxide, perovskite) that can operate with high activity and long-term stability.

Electrochemical CO2 conversion (Cu-based materials, single-atom catalyst)

Carbon capture and utilization (CCU) is drawing attention around the world as a way to solve the problem of greenhouse gas emissions and increasing energy demands. Among various efforts, the conversion of CO2 into fuels and chemical feedstocks via electrochemical methods is a representative technology of CCU.

We develop new electrochemical CO2 reduction catalysts (e.g. Cu-based (hydr)oxide, single atom catalyst) to achieve high CO2 conversion efficiency and superior selectivity for producing multi-carbon products.
