NOVELTY - Preparation of mesoporous material MRD-1 having a graphenosilicate possessing MCM topology using an ionic solid as a structure directing agent involves (a) diluting 2.4 g 1-hexadecyl-3-methylimidazolium chloride ionic solid in 50 mL deionized water under magnetic stirring, (b) adding 50 mL ethyl alcohol and 10 mL ammonium hydroxide, (c) stirring for 10 minutes, (d) adding 3.4 g tetraethylorthosilicate (TEOS) and graphene, (e) magnetically stirring at 25-200 rpm for 1-24 hours at 5-50° C, (f) filtering and washing with 50 mL deionized water thrice, and (g) drying in an oven at 100° C until constant weight. The content ratio of TEOS to graphene is 1-10%. USE - Preparation of mesoporous material. ADVANTAGE - The method is environmentally-friendly and carried out at room temperature using ionic solid which is easy to be synthesized.
