摘　　要：本文采用溶胶凝胶法将二氧化钛负载于SBA-15介孔分子筛上,成功制备了TiO_(2)/SBA-15复合催化剂,并将其应用于光催化降解亚甲基蓝的实验中。本研究详细探讨了亚甲基蓝溶液初始质量浓度、pH值、光催化反应时间以及TiO_(2)/SBA-15复合催化剂的投加量等因素对光催化降解效果的影响。In this paper,TiO_(2)/SBA-15 composite catalyst was successfully prepared by sol-gel method to load titanium dioxide onto SBA-15 mesoporous molecular sieve.This composite catalyst was then utilized in the photocatalytic degradation of methylene blue.The study extensively investigated the effects of initial concentration of methylene blue solution,pH value,photocatalytic reaction time,and the dosage of TiO_(2)/SBA-15 composite catalyst on the photocatalytic degradation efficiency.
