The present invention relates to materials and methods for preparing photocatalytic activated carbon used for the sterilization of air and water. Specifically, the photocatalyst sol is added to activated carbon alone, or the photocatalyst powder or photocatalyst sol is mixed with glucose, zeolite, activated carbon, sawdust, rice husk, waste tire, zeolite, and materials at a constant ratio to treat air and water. The present invention relates to materials and methods for preparing photocatalytic activated carbon that sterilize microorganisms or remove VOCs. According to the composition, TiO 2 sol and ZnO sol as photocatalysts are prepared and heated to 400-1000 ° C. to prepare photocatalyst activated carbon or photocatalyst (TiO 2 , ZnO) powder at a ratio of 0.5-20% sawdust, rice hull, waste TiO 2 sol and ZnO sol, which are photocatalysts, are mixed in a ratio of 0.001-100 mg / g, respectively, in sawdust, rice hulls, waste tires, and zeolite materials, or in a ratio of photocatalysts (TiO 2 , ZnO). ) Sawdust containing 0.5-20% of powder, mixed with rice husk (0.5-5%), waste tire (0.5-5%) and zeolite (0.5-5%) in a proportion, drying the moisture to 5-10% After heating it to 200-300 ℃ while putting it in an extruded screw, it is compressed and injected into a pressure of about 1 ton and injected and molded carbonized impregnated sawdust is heated at 400-1000 ℃ for 20-60 minutes in an activation furnace. Disinfect microorganisms and remove VOCs at the same time Impregnated activated carbon is used as a photocatalyst activated carbon. |
