Description

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 m²/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 CO₂ capture application. Surface functionalized MCM-41 may be used as a catalyst in the synthesis of bisphenol A.
