▎ 摘  要

NOVELTY - Preparing composite photocatalyst comprises taking the graphene oxide sheet, adding it to the surfactant solution, slowly adding part of water to obtain mixed solution, ultrasonically dispersing the graphene oxide sheet in the surfactant, adding nano titanium dioxide to it, slowly adding another part of water, adding copper-benzene-1,3,5-tricarboxylate (Cu-BTC), transferring the mixture to the hydrothermal reactor, carrying out hydrothermal reaction at 100-120℃, washing the product with water after hydrothermal reaction, drying, and grinding into powder to obtain composite photocatalyst. The composite photocatalysts are 3-5 pts. wt. graphene oxide flakes, 80-95 pts. wt. nano-titanium dioxide particles, 1-2 pts. wt. Cu-BTC powder, 2-3 pts. wt. surfactant and 77-80 pts. wt. water. The preparation of graphene-Cu-BTC co-modified titanium dioxide composite photocatalyst by hydrothermal method. USE - The photocatalyst is useful for catalysing organic pollutants under visible light (claimed) and fields e.g. sewage treatment plants and chemical plants. ADVANTAGE - The photocatalyst has better visible light activity, increased specific surface area, excellent photocatalytic performance, long-term stable catalytic performance, long service life, and excellent performance.
