Composite catalyst of MoS2/defective MIL-100 (Fe) and preparation method and application thereof

The invention discloses a composite catalyst of MoS2/defective MIL-100 (Fe) and a preparation method and application thereof. According to the composite catalys, MIL-100 (Fe) grows on MOS2 in situ toobtain a MoS2/MIL-100 (Fe) material, the MoS2/MIL-100 (Fe) material is activated at a high temperature to obtain the composite catalyst, the composite catalyst is formed by bonding MOS2 and MIL-100 (Fe), and the mass ratio of MOS2 to MIL-100 (Fe) is 0.2-0.8: 1. According to the composite catalyst, the reduction effect of Mo < 4 + > is utilized; meanwhile, the iron-based active component exposed bythe defective MIL-100 (FE) is utilized, good physicochemical properties of MoS2 and the defect type MIL-100 (Fe) are considered at the same time; a favorable way is provided for diffusion of pollutant molecules and H2O2 molecules in a Fenton-like system; the defect that the promotion effect of MoS2 composite catalysts on Fenton-like compounds in the prior art needs to depend on light conditions is overcome, the oxidation
