This research, led by Zihao Xing and Jinfa Chang from Northeast Normal University, delves into the promoting mechanism of the Ru-integration effect in RuCo bimetallic nanoparticles for enhancing water splitting performance.
The study aims to address the issue of high overpotentials in the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) during water electrolysis, which has hindered the development of this zero-carbon-emission hydrogen-generation process. Although precious metals like Ru, Ir, and their oxides are often used as anode catalysts and Pt as the cathode catalyst, and Ru-based catalysts show promise due to their similar Ru–H and Pt–H bond strengths and relatively good OER and HER properties at a lower cost, there is still a need for more cost-effective and efficient Ru-based catalysts.
