The properties of the resultant particles were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM) and thermal gravimetric analysis (TGA). The basicity of the ZIF-8 samples was measured using temperature programmed desorption (TPD). Results showed that ZIF-8 samples synthesized in the present work were thermally stable up to 700 ºC. ZIF-8 synthesized using synthesis solution contained lowest molar ratio of methanol to zinc nitrate of 86.7 possessed highest crystallinity and largest average particles sizes of ~250 nm. Besides, this sample also demonstrated highest CO2 uptake rate due to the presence of highest amount of basic site of 0.70 mmol/g among the ZIF-8 samples. © 2014 Trans Tech Publications, Switzerland. %Z cited By 9; Conference of 3rd International Conference on Process Engineering and Advanced Materials, ICPEAM 2014 ; Conference Date: 3 June 2014 Through 5 June 2014; Conference Code:114811
