“…In addition to the content and coordination state of Ti, the morphology of the TS-1 particle affects the catalytic activity of TS-1 [38]. Therefore, the development of a facile method for preparing nanosized TS-1 has long been desired.…”

“…Numerous literature reports show that microwaveassisted hydrothermal synthesis could provide an efficient method to rapidly produce various zeolite crystals and rationally control their particle size distribution [11], phase purity [12], phase transformation [13] and morphology [14]. In many cases, microwave radiation has proven to facilitate more uniform products than the conventional hydrothermal treatment [15].…”

The crystal size and shape of the silicoaluminophosphate molecular sieve SAPO-34 have been effectively controlled in the reaction system of Al 2 O 3 -P 2 O 5 -SiO 2 -TEAOH-H 2 O under microwave radiations. Nano sheet-like SAPO-34 crystals are obtained when using colloidal silica as the silica source. When TEOS is used as the source of silica, homogeneous SAPO-34 crystals with a particle size of about 100 nm are formed, and the morphology of the crystals changes from uniform nano particles (*100 nm) to microspheres (*1.5 lm) by varying the H 2 O/Al 2 O 3 molar ratio. To further investigate the morphology control of SAPO-34, the synthetic factors, such as the silica source, water content, crystallization time and aging time have been studied in detail.

“…The synthesis of porous material with microwave heating has many advantages such as fast crystallization [11][12][13][14], increased phase purity and selectivity [15,16], narrow particle size distribution [17] and facile morphology control [18,19]. Microwave heating has also been successfully applied in the synthesis of Ti-MFI [20][21][22]. Ahn et al [23,24] have developed the microwave synthesis of titanium silicalite-1 using solid phase precursors, and obtained a highly crystalline product in a short time.…”
