Abstract
The invention discloses a photo-Fenton catalyst and a preparation method and application thereof. The preparation method comprises the following steps that a Ce-MOF film structure is formed on gamma-Al2O3 firstly, after vacuum drying, the Ce-MOF film structure is dipped in an OPA solution, an alkylation reaction is conducted, then alpha-FeOOH is generated on a formed compound through an in-situ growing method, and thus the compound-type photo-Fenton catalyst is obtained. The MOF structure with hydrophobic performance is formed on the gamma-Al2O3, the adsorption performance of VOCs can be enhanced, electronic transmissibility is strengthened, Fe<3+> is promoted to be reduced into Fe<2+>, meanwhile, Ce-MOF has abundant acid sites, and generating of a photo-Fenton catalytic oxidation reactionis also facilitated. Organic groups on MOF and the in-situ growing mode of the alpha-FeOOH can prevent iron leaching, the stability of the catalyst can be further improved, and the service life is prolonged.
