Single atomic catalysts have shown great potential in efficiently electro-converting O2 to H2 O2 with high selectivity. However, the impact of coordination environment and introduction of extra metallic aggregates on catalytic performance still remains unclear. Herein, first a series of carbon-based catalysts with embedded coupling Ni single atomic sites and corresponding metallic nanoparticles at adjacent geometry is synthesized. Careful performance evaluation reveals NiSA /NiNP -NSCNT catalyst with precisely controlled active centers of synergetic adjacent Ni-N4 S single sites and crystalline Ni nanoparticles exhibits a high H2 O2 selectivity over 92...
