▎ 摘　　要

NOVELTY - Zinc oxide (ZnO) visible photocatalyst fabric doped with graphene oxide (GO) and ferric ion (Fe3+) is prepared by respectively preparing GO sol and ZnO precursor sol doped with Fe3+, mixing, soaking the processed fabric carrier in it, loading the composite precursor on the fabric by ultrasonic method, and high temperature baking and curing the composite on the fabric. USE - The ZnO visible photocatalyst fabric doped with GO and Fe3+ is used for purifying wastewater and waste gas. ADVANTAGE - The loading rate of the composite catalyst on the polyester-cotton fabric is 10-15%. The decoloring rate of methylene blue solution is more than 88% under the irradiation of simulated day light xenon lamp, and the decoloring rate after repeating for 15 times is still 84%. The powder composite catalyst has hexagonal wurtzite type structure and particle diameter of 6.5-8.5 nm, and can extend the absorption wavelength of visible light to 610 nm, which can respond to visible light to implement photocatalysis.
