The pure silicate mesoporous material, MCM-41 having hexagonally packed cylindrical channels with a centre to centre distance of ca. 45 Å may be synthesised from a preparation containing only sodium silicate solution, a surfactant template molecule, water, and some acid. The preparation was optimised initially both for heated and unheated syntheses. The effects of aging in the gel, heating time and stirring were investigated. MCM-41 materials which were stable to calcination were prepared in an...[Show more]
