▎ 摘　　要

NOVELTY - The method comprises (1) using dimethylimidazole, zinc nitrate, and graphene oxide as the solute and anhydrous methanol as the solvent, stirring to obtain zeolitic imidazolate framework-8-graphene oxide (ZIF-8-GO), (2) using zeolitic imidazolate framework-8-graphene oxide and thiourea as solutes and anhydrous methanol as solvent to form sulfur/zeolitic imidazolate framework-8-graphene oxide through stirring and adsorption, (3) pyrolyzing sulfur / zeolitic imidazolate framework-8-graphene oxide in the atmosphere of protective gas to form porous sulfur-doped carbon (S, N-C), (4) cooling sulfur-doped carbon, adding phenanthroline (Phen) and transition metal source (M) to sulfur-doped carbon to form precursor M/S, N-C-Phen, and (5) pyrolyzing the precursors of M/S and N-C-Phen in the atmosphere of protective gas to obtain single-atom catalysts. USE - Method for synthesizing single atom catalyst, which is used in electro-catalysis application of single-atom catalyst, which is useful in fuel cell. ADVANTAGE - The synthesis method is simple and efficient, can be used for large-scale synthesis of single-atom catalysts, and is suitable for the synthesis of various metal single-atom catalysts, and solves the shortcomings of complex synthesis and difficulty in large-scale preparation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a single atom catalyst.
