NOVELTY - High-efficiency catalyst comprises 40-50 pts. wt. silicon carbide, 10-20 pts. wt. triiron tetroxide, 10-20 pts. wt. titanium dioxide, 5-10 pts. wt. zirconium oxide, 1-5 pts. wt. cerium oxide, 0.5-2.0 pts. wt. graphene, 0.2-1 pts. wt. polystyrene nanospheres, 5-10 pts. wt. ferric chloride, and 50-100 pts. wt. deionized water. USE - High-efficiency catalyst for high-concentration organic wastewater treatment. ADVANTAGE - The high-efficiency catalyst improves the oxidation efficiency of the organic pollutant in the waste water, and solves the problem of difficult high concentration organic waste water treatment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing high-efficiency catalyst, which involves: (A) adding all raw materials; (B) taking first portion of deionized water and titanium dioxide to prepare a titanium dioxide slurry, adjusting the pH to 3.0-3.5, and then adding the FeCl3 solution to the slurry of titanium dioxide, forming a coating on the surface of the titanium dioxide, washing and filtering; (C) arranging silicon carbide, triiron tetroxide, zirconium oxide, cerium oxide, graphene, polystyrene nanospheres, second deionized water, and coated titanium dioxide in proportion to a slurry; and (D) subjecting provided slurry to high-speed dispersion for 1-3 hours, washing and filtering, and then heat-treating at 400-600 degrees C, then calcining at a temperature higher than 800 degrees C, and finally pulverizing to obtain a catalyst.
