The article discusses the challenge of slow kinetics in electrochemical hydrogen and oxygen redox reactions in alkaline electrolytes due to the use of expensive Pt-based electrocatalysts. Researchers have developed a method to enhance the catalytic activity per mass of Pt by modifying Pt nanoparticles with paired Pd-Ru species. By boosting the availability of Hads and OHads on the Pt surface, the specific catalytic activity for the hydrogen oxidation reaction (HOR) is significantly improved without compromising the electrochemical surface active area. The study showcases Pd-Ru@Pt nanoparticles with a high exchange current density and durability, surpassing traditional Pt-based catalysts. Various characterization techniques confirm the uniform decoration structure of Pt nanoparticles by Pd-Ru pairs. The synthesis method involves a vacuum-assisted solid-phase approach, trapping Pd and Ru precursors to create isolated Pd and Ru atoms on the Pt surface. The results demonstrate the potential of this innovative surface modification strategy to enhance the efficiency of electrocatalysts for renewable energy conversion and storage devices.
