Atomically Dispersed Pt-Ru Dual-Atom Catalysts for Efficient Low-Temperature CO Oxidation Reaction.

ABSTRACT: Single-atom catalysts (SACs) have demonstrated excellent performance in heterogeneous catalytic reactions owing to their maximized atomic efficiency, distinctive geometric, and electronic configurations. However, the efficacy of SACs remains limited for certain reactions requiring simultaneous activation of multiple reactants over metallic active sites. Herein, we report an atomically dispersed Pt₁Ru₁ dual-atom pair site anchored on nanodiamond@graphene (ND@G) for CO oxidation. The Pt₁Ru₁ dual-atom catalyst shows an exceptional turnover frequency (TOF) of 17.6 × 10^-2 s^-1 at significantly lower temperature (30 °C), achieving a tenfold increase in TOF compared to single-atom Pt₁/ND@G catalyst (1.5 × 10^-2
