▎ 摘　　要

NOVELTY - Transition metal single atom active catalyst comprises single atom transition metal as active component, active carbon, carbon nano tube, graphene, nano-diamond, any one of the graphitic carbon nitride as the carrier, after the inorganic salt precursor of the transition metal or the organic salt precursor and the carrier are adsorbed, the product is obtained. The invention also claims the application of said transition metal single atom active catalyst in the field of advanced oxidation antibiotic. USE - Transition metal single atom active catalyst. ADVANTAGE - The transition metal single atom active catalyst has excellent catalytic effect, high stability, reduces the environment pollution and cost, and has good industrial application prospect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing transition metal single atom active catalyst, which involves aking mono-atom transition metal as active component, selecting one or more of inorganic salt precursor or organic salt precursor of transition metal, dissolving respectively solution dissolved in the solvent to prepare active component, taking active carbon, carbon nano tube, graphene, nano-diamond, graphitic carbon nitride as the carrier, adding the carrier into the precursor solution of the active component obtained, stirring for 12h at room temperature to dry the solution, drying at 60?oC, taking out the material after drying, grinding and grinding for 20min, roasting for 1h in the tubular furnace to obtain the product. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of different single component transition metal single-atom catalyst.
