| Abstract: | With bentonite as a carrier,4 n-butyl titanate and high cerium sulfate as raw material,sol-gel method was used for preparation of composites photocatalyst of rare earth-doped TiO2 bentonite(RTB),with structure and morphology characterizing by XRD and SEM.Results showed that it has a high specific surface area,and there exists an obvious TiO2 anatase crystalline characteristics peaks.Catalyst dosage,initial dye concentration,illumination time,pH value and other factors on decolorization rate of neutral red d... |
