The invention discloses a multi-component accurate self-assembling S atom regulation Cu-based second shell carbon-rich-based material and a preparation method and application thereof.The preparation method of a catalyst comprises the steps that urea and sulfuric acid are stirred to react in a water solvent, the S component in the sulfuric acid is doped on urea serving as a carbon-rich-substrate precursor through the hydrogen-bond interaction, and then the carbon-rich-substrate precursor is obtained; and slowly adding a Cu ligand dispersion liquid into the sulfur-containing doped urea water suspension, carrying out a stirring reaction, carrying out rotary evaporation on the solvent, and carrying out calcination treatment in an inert atmosphere to obtain the target catalyst. According to the catalyst disclosed by the invention, the S atom regulated Cu-based second shell carbon-rich-based material is efficiently and accurately assembled through multiple component synthesis steps, and based on a non-metal regulat
