Abstract

The invention discloses a modified waste PVC-based active carbon-loaded nano arsenic sulfide composite electrode material, and is characterized by being prepared from the following raw materials in parts by weight: 1 part to 2 parts of sodium pyrophosphate, 1 part to 3 parts of polymethyl methacrylate resin, 4 to 7 parts of tetrahydrofuran, 2 to 4 parts of nano arsenic sulfide, 1 part to 2 parts of nano dysprosium sulfide, 1 part to 2 parts of beryllia, 110 to 130 parts of modified waste PVC-based active carbon, 2 to 3 parts of dextrin, 10 to 15 parts of distilled water, and 1 part to 2 parts of distearoyl isopropoxy aluminate. The preparation method provided by the invention uses waste PVC to prepare electrode material active carbon which has the advantages of large specific surface area, high conductivity and the like, resources are utilized in a rationalized manner, the problem of environmental pollution is solved, the electrode material is doped with a metallic element having a conductive function and surface coating is performed with the nitrogen element, and a prepared supercapacitor has the advantages of high specific capacitance, high charge/discharge rate, good cycle stability and long usage time.

Description

technical field [0001] The invention relates to the field of chemical energy materials, in particular to a modified waste PVC-based activated carbon-loaded nano arsenic sulfide composite electrode material and a preparation method thereof. Background technique [0002] Chlorine-containing PVC waste is difficult to degrade at room temperature, and the main treatment methods are landfill, incineration and recycled materials. The landfill method will occupy a large amount of cultivated land, the incineration method will produce a large amount of harmful smoke and HCl, and the recycled material method will reduce the product quality, the application range is limited, and the amount of waste disposal is also small. The amount of discarded plastics in my country is about 2 million tons every year. The huge amount of polymer waste has caused serious environmental pollution and waste of natural resources. Therefore, the recycling and reuse of discarded PVC has significant economic ...
