Abstract:
The flower like BiOCl/TiO2 heterojunction was synthesized by the solvothermal method. The photocatalytic performance of tetracycline-copper complex(TC-Cu)by BiOCl/TiO2 catalyst was studied. The crystal structure and morphologies of prepared photocatalysts were characterized by XRD,SEM and BET techniques,respectively. The effects of initial concentrations of TC and Cu2+ on photocatalytic performance were investigated. Meanwhile,the toxicity of degradation products was uated by the growth inhibition rate of chlorella. The results indicated that the BiOCl/TiO2 composite exhibited higher photocatalytic performance than TiO2. When the initial concentrations of TC and Cu2+ were 20mg/L and 5mg/L and reaction time was 60 min,the degradation efficiency of TC and TC-Cu reached 84.21% and 89.14%,respectively; and the mineralization rate was up to 47.49% and 40.10%. In addition,the results of toxicity test showed that the TC-Cu complex could be effectively degraded by BiOCl/TiO2.
