Electrocatalysts for CO2 and water electrolysis

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.

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

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
