| Abstract |
The high cost of electricity of water electrolysis system which is induced from large overpotential is the main challenge in fulfilling the economic requirements of the viable hydrogen energy system. Developing a great catalyst for oxygen evolution reaction (OER), which is a slower half-cell reaction of water splitting, can decrease the operational cell potential. The state-of-the-art catalysts for OER are composed of a large amount of expensive iridium, however, the iridium leaching during OER operation is a serious issue to practical application. Herein, we report the synthesis of Pt embedded RuO2 nanostructures, which are doped with transition metal (Ni or Co), namely PtM@RuO2 (M=Ni or Co). The synthesized nanocatalysts showed great catalytic activity and stability toward water splitting reaction. We also investigated the role of embedded Pt, transition metal co-catalysts, and RuO2 thin layer in the overall electrocatalytic OER. |
