  • Device and method for selective oxidation of macromolecular organic pollutants using free radicals produced in heterogeneous fenton reaction
    Patent number: 12545603
    Abstract: Disclosed is a device for selective oxidation of macromolecular organic pollutants using free radicals produced in a heterogeneous Fenton reaction. The device includes a heterogeneous Fenton reaction unit and an electrochemical cell. The heterogeneous Fenton reaction unit includes a reactor and an anion exchange membrane. The anion exchange membrane is disposed in the reactor and separates the reactor into a first chamber and a second chamber. The first chamber is filled with a catalyst and the wastewater to be treated; and the second chamber is filled with a dielectric material. The electrochemical cell is configured to supply an electric field to the reactor, so that organic acids generated by a heterogeneous Fenton reaction move from the first chamber into the second chamber.

  • Base material and preparation method thereof
    Patent number: 12521701
    Abstract: A base material includes a base layer. The base layer includes a structured surface. The base layer includes a transition metal and a transition metal oxide, and a sum of the transition metal and a transition metal oxide accounts for at least 90 wt. % of the base layer. The transition metal oxide is concentratedly distributed on the structured surface. The base material is flexible in at least one direction, and has a bending angle of not less than 90° when being bent.
