▎ 摘 要
NOVELTY - Preparing reduced graphene oxide/titanium dioxide (RGO/TiO2/Ag) aerogel type photocatalyst involves using graphene oxide, butyl titanate and silver nitrate as raw materials, followed by thermal reduction method, ultraviolet light reduction method and freeze drying method. USE - Method for preparing reduced graphene oxide/titanium dioxide aerogel type photocatalyst used for degrading formaldehyde (all claimed). ADVANTAGE - The method enables to prepare reduced graphene oxide/titanium dioxide aerogel type photocatalyst has aerogel structure, large specific surface area, strong adsorption capacity, strong structure and easy recovery, excellent photo-catalytic performance, has good chemical stability and low cost.
