▎ 摘 要
NOVELTY - A titanium dioxide and phenolic resin-containing visible light response photocatalyst is prepared by adding graphene oxide to a container, adding deionized water, ultrasonically stripping and dispersing for 0.5-10 hours, centrifuging at 4000-8000 rpm for 5-30 minutes, adding separated supernatant to other container, adding diphenol and formaldehyde, mixing, slowly dripping titanium tetrachloride under rapid stirring, reacting at room temperature for 0.5-1 hour, transferring obtained mixture to a hydrothermal reactor, reacting at constant temperature of 120-260℃ for 1-72 hours, naturally cooling, filtering, washing with deionized water and drying. Also claimed is, preparation of the titanium dioxide and phenolic resin-containing visible light response photocatalyst. The graphene oxide and phenolic resin are carried on the surface of titanium dioxide, to obtain visible light response photocatalyst with wide spectrum. USE - Titanium dioxide and phenolic resin-containing visible light response photocatalyst. ADVANTAGE - The photocatalyst is prepared by simple process, has excellent ultraviolet light response (by addition of nano-titanium dioxide), and visible light response performance (by addition of phenolic resin), and accelerates the separation and transfer efficiency of photogenerated charges with the help of excellent charge transport and transfer ability of graphene obtained after reduction of graphene oxide by hydrothermal reaction.
