This invention discloses a carbon-based composite catalytic material, its preparation method, and its applications. The invention employs a one-step carbonization process involving molten salt confinement, a non-urea nitrogen source, and no ball milling: a dinuclear iron precursor, nitrogen-containing organic matter (as both a non-urea nitrogen source and a carbon source), ZnCl2, and a molten salt system are mixed. After high-temperature pyrolysis under an inert atmosphere, the mixture is sequentially washed with hot water to dissolve the molten salt, followed by washing with HCl solution and drying. The entire process eliminates the need for complex mechanical treatments such as ball milling, simplifying the steps and providing milder conditions, making it more suitable for scale-up preparation and engineering applications. The above-mentioned carbon-based composite catalytic material is applied to the degradation of chlorinated organic pollutants in soil, particularly in conjunction with persulfate oxidants to construct an advanced oxidation system. The highly coordinated dinuclear M2N6 reaction center efficiently activates persulfate, generating sulfate radicals, hydroxyl radicals, and / or non-radical active species, achieving rapid degradation of recalcitrant chlorinated organic pollutants.

This invention belongs to the field of functional catalytic materials and water treatment technology for groundwater pollution remediation, specifically relating to a modified iron heterojunction biomass slow-release material, its preparation method, and the application of a coupled electric field in the remediation of organic pollutants in groundwater. This invention utilizes shiitake mushroom biochar as a carrier to load modified zero-valent iron, effectively alleviating the problem of iron agglomeration. The modified zero-valent iron grows in situ within the three-dimensional pores of the biochar, enabling the slow release of active iron components and improving the utilization efficiency of the oxidant. The built-in electric field of the iron-carbon structure-reinforced material helps solve the problem of slow mass transfer in groundwater media, improving the surface accessibility of the oxidant and pollutants. This material can reduce the localized Fe... 2+ Excessive concentration of oxidant leads to ineffective consumption, but the electrons can be driven by an electric field to migrate in a specific direction, achieving spatiotemporal matching and dynamic control of the electron transfer rate and the iron supply rate, forming a closed-loop system for in-situ regeneration, which has good application prospects in groundwater remediation.
