MANUFACTURING METHOD FOR NANOMETAL/PHOTOCATALYST SOL

摘要

PURPOSE: A producing method of nano metal/photocatalytic sol reacting to an LED lamp is provided to decompose contaminants by being optically activated through reacting to the LED lamp with the 395~400nm wavelength. CONSTITUTION: A producing method of nano metal/photocatalytic sol reacting to an LED lamp comprises the following steps: mixing 10~30parts of alcohol based organic solvent by weight, 50~70parts of water by weight as an aqueous solvent, 5~15parts of titanium precursor by weight, 0.5~10parts of transition metal by weight as a metal precursor, 0.5~5parts of nitric acid by weight as a catalyst, and 0.1~5parts of chelate stabilizer by weight in a reactor; and stirring the mixture at 60~90deg C for obtaining nano metal/photocatalytic colloid. The water is ionized pure water. The titanium precursor is titanium tetraisopropoxide.
