HIGH-CONDUCTIVITY THREE-DIMENSIONAL COMPOSITE MATERIAL, PREPARATION METHOD, AND APPLICATION OF HIGH-CONDUCTIVITY THREE-DIMENSIONAL COMPOSITE MATERIAL TO TREATMENT ON NITROGEN AND PHOSPHORUS ORGANIC WASTEWATER

The invention discloses a high-conductivity three-dimensional composite material, a preparation method and application of the high-conductivity three-dimensional composite material in treatment of nitrogen and phosphorus organic wastewater. The high-conductivity three-dimensional composite material comprises an MXene nanosheet carrier, molybdenum disulfide nanosheet clusters, nanoscale zero-valent iron intercalation particles and carbon nanotubes. The MXene nanosheet carrier and the molybdenum disulfide nanosheet are mutually intercalated to form petal-shaped three-dimensional nanosheet layer structures, the carbon nanotubes are grafted among the petal-shaped three-dimensional nanosheet layer structures, and the petal-shaped three-dimensional nanosheet layer structures extend around the carbon nanotubes serving as a framework in the one-dimensional linear direction. And nano zero-valent iron is uniformly adsorbed on the surface of the petal-shaped three-dimensional nano lamellar structure. The preparation method comprises three steps of etching and lamella stripping, three-dimensional structure intercalation and catalytic functional structure self-assembly. The three-dimensional composite material provided by the invention is of a microcosmic screen cloth sample structure, has the advantages of good conductivity, remarkably improved oxidation complex breaking performance, enhanced adsorption performance and higher material stability, and has a wide application prospect in nitrogen and phosphorus wastewater treatment.
