NOVELTY - Preparing a visible light catalytic functional fabric of bismuth vanadium oxide intercalated graphene oxide involves immersing pure cotton fabric in carboxymethyl chitosan finishing solution, drying it at 80-100 degrees C, and baking it at 150-180 degrees C for 1-3 minutes to obtain carboxymethyl chitosan modified cotton fabric. The modified cotton fabric is added to ultrasonically dispersed graphene oxide solution to pH value is adjusted to 7-8.5, and ultrasonic reaction is carried out at a temperature of 50-60 degrees C for 12-24 hours, and washed with water to make it neutral. USE - Method for preparing a vanadium oxide intercalated graphene oxide visible light catalytic functional fabric. ADVANTAGE - The method enables to prepare a vanadium oxide intercalated graphene oxide visible light catalytic functional fabric, which has low cost, small damage on textile strength, antibacterial effect, does not cause secondary pollution, is easy for industrial production, and has good air purifying effect. DETAILED DESCRIPTION - The obtained cotton fabric is vacuum dried to obtain enhanced graphene modified cotton fabric. The sodium metavanadate, enhanced graphene modified cotton fabric and bismuth nitrate are added sequentially to a phosphate buffer solution under stirring condition for 30-60 minutes to obtain a deep green solution, where molar ratio of sodium metavanadate to bismuth nitrate is 1:2. The pH value of deep green solution is adjusted to 7-8 with an alkaline solution, heated to 80-100 degrees C for 10-20 hours, and then fabric is removed at 80 degrees C to obtain a vanadium oxide intercalated graphene oxide visible light catalytic functional fabric.
