产品介绍：一般描述 介孔结构二氧化硅（MCM-41）是低密度有序介孔硅酸盐体系的一部分，该体系具有2D六方相，其是在季铵卤化表面活性剂存在下进行制备。它的孔有序且大，直径在1.5-10 nm之间，比表面积为1500 m 2 /g。 应用 MCM-41可作为基底材料，与铂配合物组装形成发光氧传感材料。它也可以用作捕获CO 2 的吸附剂。表面官能化的MCM-41可用作双酚A合成中的催化剂。 General Description Silica, mesostructured (MCM-41) is a part of low-density organized mesoporous silicate system which has a 2D hexagonal phase, prepared in the presence of quaternary ammonium halide surfactant. It has ordered and large pores with diameter in the range 1.5-10 nm and specific surface area of 1500 m 2 /g. Application MCM-41 may be used as a base material that can be assembled with platinum complexes to develop luminescent oxygen sensing materials. It may also be used as an adsorbent in CO 2 capture application. Surface functionalized MCM-41 may be used as a catalyst in the synthesis of bisphenol A.
