We are conducting technological research to develop high-performance catalyst materials

that help carbon dioxide to be efficiently recombined to convert it into high-value compounds using electrical energy.

Non-noble Metal based

Electrocatalysts for CO₂RR


The electrochemical reduction of CO₂ using renewable electricity is an
important future CO₂-to fuels/chemicals process, which converts the greenhouse gas CO₂ directly into useful chemicals, polymer precursors, and
fuels, such as carbon monoxide (CO), acetaldehyde, ethylene, and ethanol. However, the CO₂RR faces formidable obstacles with respect to
commercialization due to its low efficiency and poor selectivity.
Our research has been dedicated to identifying efficient and selective
catalysts for CO₂RR. Our studies highlight the need for a concomitant
consideration of factors related to intrinsic catalytic activity of the active
phase, its porous structure and its hydrophilicity/phobicity to achieve
a sustained high product yield.

Noble Metal based
Electrocatalysts for OER

There is a growing interest in clean energy because of problems such as
environmental pollution in the current energy supply and demand
system based on fossil fuels. Particularly, researches for using as a clean energy source using electrochemical water splitting are being actively
carried out. Among them, inhibitor of the efficiency of water splitting
reaction is a large overpotential on the anode and is the catalyst
instability in the oxidation condition. Our research group is evaluating
the performance by synthesizing Noble metal-based catalysts to ensure
excellent performance and stability. Furthermore, various research
equipment are being used to investigate the relationship between
various oxidation states and activity catalyst.

Non-noble Metal based

Electrocatalysts for OER


Both computational and experimental studies have recently shown that
the noble metal-based oxides such as Ir and Ru are most active
electrocatalysts for OER. However, high cost and scarcity of these noble
metal-based materials hinder their large-scale application. To overcome
this problem, Our lab focused to develop non-noble metal-based
electrode for OER. Our simple and scalable method appear to be
promising method to ensure economic feasibility.
