The invention belongs to the technical field of solid waste recycling treatment, and discloses a method for preparing a two-dimensional alloy/carbon composite nano material by using electroplating and organic sludge. Mixing electroplating sludge, organic sludge and inorganic salt, heating and stirring until the water is evaporated to dryness, depositing to obtain a precursor containing a metal component/an organic carbon component/the inorganic salt, grinding, roasting in a protective atmosphere to obtain an alloy nanoparticle/carbon @ inorganic salt compound, adding the alloy nanoparticle/carbon @ inorganic salt compound into water to dissolve an inorganic salt template, and separating and recovering a black substance floating on the surface of the solution to obtain conductive graphite carbon; and centrifuging the residual mixture to obtain the two-dimensional alloy/carbon composite nano material, and concentrating the residual inorganic salt solution for recycling. The method not only improves the utilization rate of resources, but also provides a scheme with economic benefit for solving the two solid waste pollutions. |
