以自制二元共聚物聚[苯乙烯-3-（甲基丙烯酰氧）丙基三甲氧基硅烷]改性MCM-41，并以其为载体制备铁基非均相催化剂。研究了该催化剂对亚甲基蓝的催化降解性能，同时利用FT-IR、XRD、SEM、NH₃-TPD、氮气等温吸附（BET）等手段分析了分子筛改性后对铁基催化性能的影响。结果表明，改性MCM-41负载铁基催化剂具有优异的催化降解亚甲基蓝性能，25 min时去除率达到81.2%，与纯MCM-41负载铁基催化剂相比，性能提高了33.9%。

Iron-based heterogeneous catalysts are synthesized by using poly(styrene-3-methacryloxy propyltrimethoxy silane) modified MCM-41 as support.The activity of the catalyst to degrade methyl blue is investigated systematically.FT-IR,XRD,SEM,NH₃-TPD and nitrogen isothermal adsorption (BET) are utilized to analyze the effect of modified MCM-41 on catalyst performance.It is indicated that the modified MCM-41 supported iron-based catalyst shows excellent performance in the degradation of methylene blue,over which the removal rate reaches 81.2% in 25 minutes,which is 33.9% higher than the performance of pure MCM-41 supported iron-based catalyst.
