摘　　要：Purely siliceous MCM 41 with a narrow pore-size distribution , different pore size , high surface area was synthesized . As prepared , calcined and catalytically tested MCM 41 materials have been comprehensively characterized by N2 adsorption/desorption at 77K and 129Xe NMR . By adding mesitylene during the synthesis , the pore size of MCM 41 was enlarged to 5.2nm. The chemical shift in 129Xe NMR spectroscopy of adsorbed xenon indicates that the MCM 41 is one dimensional pore channels .Purely siliceous MCM 41 with a narrow pore-size distribution , different pore size , high surface area was synthesized .
