Abstract
Hierarchically ordered mesocellular mesoporous silicas (HMMS) were swiftly synthesized using P123 and sodium silicate as a silica source within an hour by applying microwave irradiation without pore expander. The XRD, TEM and BET studies demonstrated that materials as-synthesized and calcined have the hierarchically ordered mesocellular structure with two different sizes about 10 nm and 30 nm pores having a minimized micropore volume compared with conventional hydrothermal method. Moreover, the HMMS sample prepared by microwave-assisted hydrothermal method had higher surface area than that of conventional hydrothermal method. The variation of the pore size and morphology of mesocellular structure varied with the aging time.
