▎ 摘　　要

NOVELTY - Preparing reduced graphene oxide supported metal single atom catalyst comprises (i) ultrasonically dispersing the graphene oxide in dimethyl sulfoxide organic solvent to obtain graphene oxide dispersion liquid, (ii) dissolving the metal precursor in dimethyl sulfoxide to obtain metal precursor solution, and (iii) mixing the graphene oxide dispersion liquid and metal precursor solution, stirring to mix uniformly, placing in the magnetic stirring reaction kettle, and carrying out solvent thermal reaction at 130-150 degrees C, completely reacting, washing the product with ethanol and de-ionized water for multiple, and freezing and drying to obtain the reduced graphene oxide loaded metal single atom catalyst. USE - The method is useful for preparing reduced graphene oxide supported metal single atom catalyst. ADVANTAGE - The catalyst: has excellent catalytic performance and stability in the electro-catalysis synthesis ammonia field.
