The mesoporous molecular sieve (MCM)-41 using ionic liquid as template has been prepared.The typical template of ionic liquid Was[C16mim]X.In thiS article,the use of 1-alkyl-3-methylimidazolium([Cnmim]Br,where n=12.14,16,18,20)salts as templates in the synthesis of MCM-41 is reported.The results showed that the synthesized MCM-41 had uniforlTl pore diameter,high surface area and stable framework.The largest surface area of MCM-41 Was the one prepared with [C14mim]Br as template.When using[C18min]Br as template,the narrowest pore distribution sample Was obtained and the effect of surface tension of template solution to MCM-41 Was first discussed.
