High efficiency and low cost catalyst for water electrolysismartes, 27 febrero 2018 A research team led by Professor Sangaraju Shanmugam of Science and Energy Engineering at DGIST has developed highly efficient and durable nanostructured core-shell electrocatalyst and successfully replaced the precious anode in water electrolysis, through collaboration with the group of research of the Pacific Northwest National Laboratory (PNNL).The substitution of conventional fuels for renewable energy resources is an adequate approach to achieve an ecological environment and reduce future energy demands. Therefore, the generation or conversion of electrochemical energy into renewable energy devices, which depends on the anode and cathode reactions, has received a lot of attention.In the electrocatalytic water division, oxygen gas is generated at the anode due to the oxygen evolution reaction (OER), a slow electrochemical reaction compared to the hydrogen evolution reaction (HER). Therefore, a suitable electrocatalyst is needed for the stable electrocatalytic water division.
