中文摘要：

采用一步晶化法合成了具有MCM-41介孔分子筛结构的CoAPSO分子筛．用X射线粉末衍射（XRD）、元素分析（ICP）、氮气吸附、透射电镜（TEM）、紫外可见漫反射光谱（UV—Vis）和热重分析（TG）等对样品进行了表征．合成的样品热稳定性高，孔径大约在2．5nm左右．钴原子以四配位形式进入介孔孔壁中；随着钴含量增加，样品的孔径减小，孔壁增厚．在环己烷氧化反应中，所合成的CoAPSO分子筛显示出较高的催化活性和环己酮选择性；当钴含量为0．34％时，单位钴原子上环己烷的转化数达到420．5．

英文摘要：

Mesoporous molecular zation and characterized by XRD, sieve CoAPSO with MCM-41 structure TEM, ICP element analysis, nitrogen was synthesized through one-step crystalli- sorption, UV-Vis spectra and thermogravimetric （TG） analysis. The results suggested that the heteroatom cobalt was incorporated into the pore wall of MCM- 41. CoAPSO as-prepared exhibited high thermal stability and a pore dimension of 2.5 nm. With the increase of Co content in CoAPSO, its pore size decreased and the wall thickness increased. The material CoAPSO as a catalyst exhibited high activity and cyclohexanone selectivity in cyclohexane oxidation under mild conditions with molecular oxygen as oxidant; the turnover number （TON） reached 420.5 for CoAPSO with a cobah content of 0.34%.
