▎ 摘　　要

NOVELTY - Synthesizing carbon-loaded single-atom catalyst by thermal shock comprises dissolving metal salt and ligand in organic solvent to obtain mixed solution, adding carbon source in the mixed solution, uniformly dispersing and grinding to obtain precursor, performing surface impurity removal treatment on the conductive substrate, placing the precursor on the conductive substrate, under the protective gas atmosphere, using electrode power supply to electrify, heating the precursor for multiple times in the preset time, and collecting the product, where the metal salt comprises at least one of nickel salt, chromium salt, manganese salt, iron salt, cobalt salt, copper salt, zinc salt, molybdenum salt, silver salt, ruthenium salt, palladium salt and platinum salt. USE - The method is useful for synthesizing carbon-loaded single-atom catalyst by thermal shock. ADVANTAGE - The method is capable of synthesizing the carbon-supported single-atom catalyst with excellent thermal shock resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for carbon-loaded single-atom catalyst obtained by the above-mentioned method.
