【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-15 1.0 g/L,H₂O₂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。更多还原

【Abstract】 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 optimal conditions were as follows: MB initial mass concentration 3 mg/L, pH 4, CuPc/SBA-15 1.0 g/L, volume fraction of H₂O₂ 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.更多还原
