MCM-48分子筛的合成及在催化领域的应用进展

Progress in Synthesis and Catalytic Application of MCM-48 Molecular Sieve

自从M41S系列分子筛问世以来，介孔分子筛的合成和应用研究便成为热门领域之一．其中MCM-48具有～2．6nm的均匀孔径、三维螺旋面的孔道结构、良好的长程周期性和稳定的骨架结构^[1-3]．

MCM-48 containing a three-dimensional network has potential applications as versatile catalyst,molecular sieves,or as host structures for nanometer -sized guest compounds because of its insensitivity to blockage,which is a great advantage in comparison with MCM-41.
