Preparation of Silicious Mesoporous Spherical and Rod- Like MCM-41 Using Cetyltrimethylammonium Bromide as the Structure Directing Agent

MCM-41 is one of the groups of mesoporous materials that have wide applications as adsorbents, ion exchangers and catalyst supports. In this work spherical and rod-like MCM-41s were synthesized in homogeneous and heterogeneous reaction media, respectively. For synthesis of these materials the cation...
