Abstract

AgBr/Ag2CO3 composite as photocatalyst was synthesized via a facile one-step coprecipitation method by adding different contents of CTAB as Br source,and characterized by XRD,SEM,UV-Vis DRS and PL.The photocatalytic activity of the as-synthesized AgBr/Ag2CO3 composite were explored by the removal of the photocatalytic degradation of methylene blue(MB) aqueous solution under illumination of visible-light.The effects of coprecipitation time and quality added of CTAB on the catalytic performance of the samples were also investigated.The results revealed that AgBr/Ag2CO3 composite shown a superior photocatalytic behavior than those of the single-phase AgBr or Ag2CO3 due to the photo-produced e- of AgBr may be transferred into Ag2CO3.Among these composites,0.08g AgBr/Ag2CO3 composite obtained with 0.3g CTAB,and co-precipitation time of 1h,shown the highest degradation rate with 99.19% removal efficiency of MB within 30min.More importantly,the recycling tests proved that the degradation rate of methylene blue can reached 60.91% after cycled for three times.
