The combined effect of hydrothermal treatment temperature and aging time on the structural properties of ordered mesoporous KIT-6 material were investigated. A series of KIT-6 materials were prepared by hydrothermal synthesis procedure. In the first step, experiments were performed at 90oC and at different aging times (0-72 h) to understand the effect of hydrothermal aging time. It was concluded that the aging time positively affect the formation of ordered mesoporous structure and uniform pore structure occurs after 18 h. In addition, long hydrothermal treatment time favored the pore enlargement. In the second step, to understand which parameter (time or temperature) is more important in the synthesis of highly uniform material, KIT-6 materials were prepared at different temperatures ranging between 60-150oC and at different aging times (24 h and 72 h). The experiments showed that at elevated temperatures (>90oC) long aging times negatively affect the structural properties of the mesoporous KIT-6 structure. Highly uniform mesoporous KIT-6 material having high crystallinity, narrow pore size distribution, high BET surface area (726 cm3/g) and high pore volume (1.5 cm3/g) was prepared at 120oC with an aging time of 24 h. However, it was determined that 60oC is not a suitable temperature to obtain KIT-6 material having good structural properties and the uniform crystal structure deteriorated at 150oC.
