The invention relates to a supported advanced oxidation catalyst coated with molecular sieve-based nano-carbon, comprising: 60-70wt% molecular sieve, 10-15wt% binder (in oxide form), 15-25wt% nano-carbon and 2-10wt% Transition metal oxides; molecular sieves are Beta, ZMS‑5, MCM‑22, MCM‑41, SAPO‑34, SSZ‑13 or Y type molecular sieves; binders are pseudoboehmite, high clay or silica sol; transition The metal oxide is an oxide of Mn, Cu, Co or Ni. The beneficial effects of the present invention are: the supported advanced oxidation catalyst of the present invention can efficiently activate ozone to form OH radicals in the advanced oxidation reaction, and the OH radicals are mainly used in the ozone catalytic oxidation process to remove organic pollutants, especially for coal Improvement and modification of chemical wastewater; to solve the problems of poor reaction performance of existing ozone catalysts and low removal efficiency of organic matter in practical application. |
