abstract: DDR3 zeolite has been attracted by the researchers for its characteristics which are potential in various applications including CO2 adsorption. Thus, in the current work, DDR3 zeolite synthesized via ultrasonic irradiation method reported in our previous work 14 are characterized by BET surface area and tested for CO2 adsorption at room temperature. DDR3 sample synthesized in 10 days via hydrothermal heating and ultrasonic pre-treatment of 3 h showed the BET surface area of 297 m2/g with CO2 adsorbed amount of 1.86 mmol/g (28 cm3/g STP). Subsequently, samples synthesized in 1 day and 0.5 day with ultrasonic pre-treatment of 1 h showed the BET surface area of 201 m2/g and 2.0 m2/g, respectively, with CO2 adsorbed amount of 1.61 mmol/g (14 cm3/g STP) and 0.3 mmol/g (2 cm3/g STP), respectively. Subsequently, reference DDR3 sample which was synthesized in 25 days as reported in literature showed the BET surface area of 323 m2/g with CO2 adsorbed amount of 1.91 mmol/g (31 cm3/g STP). Consequently, in the present work, it was observed that BET surface area and CO2 adsorption decreases with decrease in synthesis duration. This result was mainly because of the effect of growth duration and ultrasonic pre-treatment. Overall, it was concluded that DDR3 zeolite synthesized in 1 day via ultrasonic irradiation coupled with hydrothermal heating method showed comparable CO2 adsorption results with the DDR3 reference sample obtained in the present work as well as the DDR3 samples reported in the literature. © 2016 The Authors.
