▎ 摘　　要

NOVELTY - An easily-recycled and reusable organic dye photocatalyst compound is prepared by mixing graphene oxide solution, titanium isopropoxide, sulfuric acid and alcohol to obtain mixed liquor; heating the mixed liquor and conducting reaction to obtain graphene-titanium dioxide compound; and mixing the graphene-titanium dioxide compound, the solution that contains ferrous (Fe2+) and ferric (Fe3+) ions and the solution that contains hydroxyl (OH-) ion, and heating and conducting reaction to obtain the photocatalyst compound. USE - Method for preparation of an easily-recycled and reusable organic dye photocatalyst compound (claimed). ADVANTAGE - The method provides photocatalyst compound having good structural stability, and higher degradation rate for organic dye.
