Photoelectrocatalysis anode material for removing phthalates and treatment method
ActiveCN110921786AAchieving Oxidation RemovalPromote degradationPhysical/chemical process catalystsWater/sewage treatment by irradiationNatural organic matterMicrosphere
The invention relates to a photoelectrocatalysis anode material for removing phthalates and a treatment method. The photoelectrocatalytic anode material is synthesized through three steps: firstly, modifying pseudo template molecules on the surface of silicon dioxide microspheres or polystyrene microspheres; arranging the modified microspheres into a three-dimensional array with an opal structurethrough a self-assembly method, finally filling gaps among the microspheres with a titanium dioxide sol-gel precursor, removing the pseudo template and the microspheres through high-temperature annealing and also forming titanium dioxide crystals. The titanium dioxide photoelectrocatalytic anode material imprinted by the pseudo template is used for removing phthalate pollutants. Compared with thematerials in the prior art, the photoelectrocatalytic anode material has special affinity for phthalate pollutants and can realize preferential removal of phthalate. In a complex system, the completeremoval of the phthalates can still be realized even under the interference of natural organic matters with the concentration of 1000 times.
