Preparation method of Fe-OMS-2 catalyst and application of Fe-OMS-2 catalyst in degradation of organic pollutants

The invention discloses preparation of a Fe-doped OMS-2 catalyst and application of the Fe-doped OMS-2 catalyst in degradation of organic pollutants. The Fe-OMS-2 catalyst is prepared by simply refluxing, filtering, washing, drying and calcining a mixed solution of manganese sulfate, ferric nitrate, concentrated nitric acid and potassium permanganate. The prepared catalyst can catalyze a peroxymonosulfate to generate sulfuric acid free radicals and hydroxyl free radicals. Sulfate free radicals and hydroxyl free radicals have strong oxidizing property and can oxidize and degrade organic dyes, and the catalyst can be recycled through simple filtration and washing after reaction. The preparation method of the catalyst is simple, and the obtained catalyst can continuously and efficiently activate peroxymonosulfate for multiple times at room temperature to degrade organic pollutants, can be recycled and reused after reaction, conforms to the concept of green development, and has great application prospects in the
