Abstract

The mesoporous molecular sieves MCM41 were prepared using room temperature ionic liquid RTIL synthesized in laboratory and cethytrimethylammonium bromide CTAB as compound templates for the first time They were prepared under low aging temperature and short aging time Via characterizing by XRD and nitrogen adsorption instrument MCM41 synthesized by this new method exhibited good crystal structure and narrow pore distribution The following preparatory conditions was optimal the molar ratio of RTIL to CTAB was 1010 aging at 80 °C for 40 h and calcined at 540 °C It is found that the acidified MCM41 improves its activity as catalyst over the unmodified ones
