METHOD FOR MANUFACTURING A COMPOSITE VISIBLE LIGHT PHOTOCATALYST OF N-DOPED TiO_2 AND N-DOPED TiO_2 USING UREA

摘要

PURPOSE: A method for manufacturing a composite visible light photocatalyst of N-doped TiO_2 and N-doped TiO_2 is provided to synthesize a large amount of N-doped TiO_2 without separate expensive equipment.;CONSTITUTION: A method for manufacturing a composite visible light photocatalyst of N-doped TioO_2 and N-doped TiO_2 comprises: a step 1 of mixing a TiO_2 precursor and alcohol; a step 2 of mixing alcohol, an acid catalyst, and water; a step 3 of mixing water and urea; a step 4 of mixing the mixture of step 1 and the mixture of step 2; a step 5 of adding the mixture of step 3 into the mixture of step 4; a step 6 of annealing the mixture of step 5; a step 7 of adding an alkaline material into the mixture of step 6 and generating a precipitate; a step 8 of drying and plasticizing the precipitate; and a step 9 of adding a precursor of a metal oxide to water or alcohol.;COPYRIGHT KIPO 2013
