Preparation of photocatalytic self-cleaning graphene oxide/titanium dioxide composite films for oil-water emulsion separation †

Key Points

• The research aims to develop a novel photocatalytic composite film for effectively separating oil-water emulsions.
• Utilized graphene oxide as the base material.
• Modified graphene oxide by grafting with polydopamine and aminosilane.
• Incorporated nano-titanium dioxide into the composite.
• Tested the photocatalytic performance of the films under light exposure.
• Achieved successful separation of oil-water emulsions using the composite films.
• Demonstrated enhanced self-cleaning properties due to the photocatalytic activity.
• Improved stability and effectiveness under various operational conditions.
