Abstract

Nanosized zeolite Y has been successfully synthesized within 4–7 h of crystallization at 100 °C at atmospheric pressure through the optimization of molar composition using 23 factorial methods The smallest crystal size of zeolite Y was in the range of 150–200 nm with the reaction time of 3 hrs to 4 hrs However solid state Si29nmr clearly shows that as aging time increases Al seems to be more incorporated into silicate framework Like the conventional zeolite synthesis the alkalinity plays a critical role in the aspect of controlling the crystal size but the other two Al2O3 and H2O contents must be considered simultaneously Therefore the 23 factorial methods can be a useful tool for the optimization of molar composition to synthesize nanosized zeolite Y crystals
