摘　　要：利用浸渍法将苯乙氧基酞菁铜(CuPc)负载到SBA-15分子筛上制备CuPc/SBA-15催化剂,利用UV-Vis、FT-IR、TG/DTG、XRD、BET、TEM等进行表征。探究不同条件下催化剂对亚甲基蓝(MB)的光催化降解性能,优化条件:MB初始质量浓度3 mg/L,pH 4,CuPc/SBA-151.0 g/L,H_(2)O_(2)体积分数1.0%。优化条件下,降解率为87.32%,重复使用5次后降解率仍可达82.19%,说明催化剂具有良好的催化活性和稳定性。CuPc/SBA-15 catalyst was synthesized by impregnating copper phenethyloxy phthalocyanine onto SBA-15 molecular sieve,and characterized by UV-Vis,FT-IR,TG/DTG,XRD,BET,TEM.The photocatalytic degradation of methylene blue(MB)by this catalyst was investigated under different conditions.The opti⁃mal conditions were as follows:MB initial mass concentration 3 mg/L,pH 4,CuPc/SBA-151.0 g/L,volume fraction of H_(2)O_(2)1.0%.Under these conditions,the degradation rate was 87.32%,and the degradation rate can still reach 82.19%after 5 times of reuse,indicated that the catalyst had good catalytic activity and stability.
