The modified MCM-41 with Poly（styrene-3-methacryloxy propyltrimethoxy silane） supported iron-based hetero-geneous catalysts were synthesized and worked as support.The iron-based heterogeneous catalysts were prepared by impregna-tion,in situ loading and NaBH4 reduction for loading active metals.The activity of the three kinds of catalysts for degradation of methylene blue was systematically investigated.The results showed that among the catalysts, the catalyst prepared by impregnation showed the best activity with 81.2% removal rate of methylene blue at 25 min.At the same time,XRD,TEM,FTIR, XPS and mercury porosimetry were employed to investigate the reason of excellent catalytic performance.The characterization result indicated that synergistic effect of the interaction between Fe and modified MCM-41 and the pore structure of catalyst were responsible for catalytic performance.
