Abstract：N-SnO2 photocatalyst was prepared by sol-gel method in N2 atmosphere,and its characterization was carried out by means of XRD,SEM,UV-Vis and other means.N-SnO2 is rutile structure,the specific surface area is 48.3 m2/g,the pore size is mainly distributeed in 5.7 nm,the band gap of N-SnO2 is 3.1 eV,which can absorb ultraviolet light and part of visible light.Using silica sol/potassium silicate solution with fluorocarbon emulsion mixed by binder,and then adding N-SnO2 and defoaming agent,thickening agent,dispersing agent and other additives to the base material and stirring grinding evenly,the SnO2 photocatalytic coatings were prepared.The photocatalytic degradation effect of NO on SnO2 photocatalytic coatings was investigated,and results show that the NO photocatalytic degradation efficiency of SnO2 photocatalytic coatings was up to 38.5％.
