▎ 摘　　要

NOVELTY - Bismuth and graphene oxide co-doped light photocatalytic material preparation involves configuring an aqueous graphene oxide solution and ultrasonic dispersion, adding cerium nitrate, absolute ethanol and acetic acid with stirring, and then adjusting pH with nitric acid to obtain a solution A. The same volume of absolute ethanol is added in the anhydrous ethanol, where the same volume of solution A is mixed with butyl titanate to form a solution B. The obtained solution B is added to the obtained solution A with stirring uniformly to form a sol. The hollow microbeads are uniformly mixed with the obtained sol, and then filtered, dried, and sintered to obtain the light photocatalytic material. USE - Method for preparing bismuth and graphene oxide co-doped light photocatalytic material. ADVANTAGE - The method prepares the bismuth and graphene oxide co-doped light photocatalytic material in a simple, cost-effective and eco-friendly manner with improved photocatalytic ability of the photocatalytic material by using ion doping. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic flowchart of the method for preparing bismuth and graphene oxide co-doped light photocatalytic material.
