Abstract：The precursor was obtained from using zinc acetate,anhydrous ethanol and diethanol amine as complexing agent by sol-gel method.ZnO and ZnO/C photocatalyst were prepared using the precursor through calcination in air and N2 atmosphere,respectively.The ludox/potassium silicate and fluorocarbon paint emulsion was binder to fabricate the ZnO and ZnO/C photocatalytic coatings.The ZnO and ZnO/C photocatalysts were characterized by XRD,SEM and UV-Vis.The properties of coating and the effect of NO abatement were investigated.The results indicated that the mass content of C in ZnO/C photocatalyst was 8.0％.The ZnO structures in ZnO and ZnO/C both were hexagonal wurtzite,and the ZnO structures in ZnO/C was hexagonal threadiness.The specific surface area of ZnO/C is 24.5 m2/g.The optical absorption edge of ZnO/C is 408 nm and the band-gap energy reduces to 2.96 eV.The photocatalytic activity test results showed that the NO reduction rate of photocatalytic coatings incorporating 1.0％ of ZnO and ZnO/C were 37.8％ and 77.5％ under xenon lamp irradiation within 70 min.
