Efficient catalytic oxidation desulfurizer as well as preparation method and application thereof

The invention provides an efficient catalytic oxidation desulfurizer and a preparation method and application thereof, a desulfurization active component cobalt phthalocyanine is loaded on the surface of a molecular sieve with rich specific surface area, and desulfurization of sulfur-containing waste gas is realized. The preparation method comprises three steps of activation of hydroxyl groups on the surface of a molecular sieve, silane coupling agent modification of the molecular sieve and loading of cobalt phthalocyanine on the molecular sieve, and finally the cobalt phthalocyanine-loaded efficient catalytic oxidation desulfurizer is obtained. The molecular sieve is modified, so that cobalt phthalocyanine is linked to the surface of the molecular sieve in a chemical bond manner, and an ultrasonic impregnation method is adopted, so that a desulfurization active component cobalt phthalocyanine is dispersed on the surface of an adsorption desulfurization agent as far as possible. The desulfurizer can efficient
