carrier is hardly applied for practical production due to its low surface area. Using special methods can achieve large surface area particles as nano-CeO 2 , but it is easily sintered and pore collapsed because of its poor mechanical strength. Therefore

Introduction MCM-41 silica materials, with their uniform mesoporous channel structure and high specific surface area, are of particular interest as catalyst supports [ 1 – 3 ]. A wide variety of metal ions (Fe, Ti, V, Cr, Cu
