  • Patent number: 6805739
    Abstract: A method of manufacturing a photo-catalyst including titanium dioxide and silicon dioxide is provided, wherein titanium dioxide is synthesized by a collosol gelatinization utilizing the water generated by the esterification of acid and alcohol to conduct a reaction of hydrolysis condensation. The silicon dioxide is synthesized by a collosol gelatinization by adding Si(OC2H5)4, n-C4H9OH and water or Si(OC2H5)4, (CH3)Si(OC2H5)3 and water.
