Abstract

Using ZnSO4·7H2O as precursor and stellerite as carrier,ZnO/stellerite photocatalytic composites were prepared by direct deposition.The phase compositions,aperture character and micromorphology of the as-prepared composites were char-acterized by XRD,BET and SEM,respectively.In addition,the effects of ZnO loading amounts and calcination temperatures on the degradation properties of methylene blue of nano-ZnO/stellerite photocatalytic composites were investigated.The re-sults showed that the composite material realized the close combination and effective dispersion of hexagonal lead zinc oxide and pyroxene,and the composites′ structure effectively inhibited the recombination of photogenerated-carrier,improved the adsorption performance and photocatalytic efficiency of the material.With 30%(mass ratio of ZnO to stellerite) ZnO loaded and calcination temperature of 300 ℃,the composite exhibited the best photocatalytic performance.
