1. Bimetallic catalysts often have a synergistic effect that makes the catalyst superior to either monometallic component

2. Bimetallic nanoparticles have gained broad interest in various fields (1, 2), particularly heterogeneous catalytic reactions such as CO oxidation (), reforming of hydrocarbons (), and transformation of CO 2 to fuel and chemicals ().Distinct from monometallic materials, Bimetallic nanoparticles often exhibit unique catalytic properties that cannot be accessed in their constituent

3. In brief, a series of [email protected] catalysts with different Pt–Co Biatomic arrangement are precisely synthesized by an in situ reduction-fusion method, achieving Pt–Co structural evolution from a Pt/Co individual monometallic islet (A-700 °C) to PtCo heterodimer (A-800 °C) and then a PtCo alloy (A-900 °C) embedded on nitrogen-doped carbon
