The Zeolite Beta was synthesized within 4hours under microwave irradiation without fluoride as a mineralize agent. During the microwave synthesis at powers from 300 to 1200 W, zeolite Beta nanocrystals were formed and spontaneously assembled into 40 to 70 nm. The zeolite Beta-1200 W possesses surface area of 463 m2/g and pore volume of 0.28 cm3/g-1. This zeolite Beta gave the highest CO2 adsorption of 2.16 mmol/g at 1 atm, 40 oC, and showed outstanding catalytic performance in the Friedel-craft acylation of anisole with acetic anhydride due to having large amount of acid site. |
