Synthesis of mesoporous MCM-41 materials at room temperature using less expensive polymeric version of ethyl silicate (40wt% SiO 2 ) as a source of silica was established. The influence of crucial synthesis parameters such as molar ratios of H 2 O/NH 4 OH, NH 4 OH/SiO 2 and CTMABr/SiO 2 in gel on the quality of the phase formed was investigated. Powder...
