Chiang, Chao-Lung published the artcileEnhancement of CO2 adsorption and separation for non-porous Zn/Co azolate frameworks via ethanol-induced structural transformation, Application In Synthesis of 104-01-8, the main research area is carbon dioxide zinc cobalt azolate adsorption separation.
Non-porous zinc/cobalt azolate frameworks with diamond-type crystal structure (MAF-31/ZIF-D-CoM) have been synthesized in large scale with an acid-catalyzed process. Afterward, an ethanol exposure process was applied for 1, 7, and 14 days to transform MAF-31/ZIF-D-CoM into porous T-MAF-4/T-ZIF-67. Two porous zinc/cobalt azolate frameworks standards (MAF-4/ZIF-67) with sodalite-type crystal structures were prepared with a solvent-free method for comparison with T-MAF-4/T-ZIF-67. Effects of ethanol vapor exposure on structual transformation of MAF-31/ZIF-D-CoM were characterized throughly. Obvious structural transfomations between non-porous and porous zinc/cobalt azolate frameworks were found with X-ray diffraction (XRD), Field-emission scanning electron microscope (FE-SEM), and X-ray absorption near-edge structure/extended X-ray absorption fine structure (XANES/EXAFS) spectra. After the 14-day ethanol vapor exposure, the CO2 adsorption uptakes of MAF-31 and ZIF-D-CoM in low/high pressures were enhanced from 5.18 × 10-5/0.68 and 1.20 × 10-4/0.18 to 1.76 × 10-3/8.27 and 1.99 × 10-3/11.2 mmol/g, resp. The CO2 selectivities of MAF-31/ZIF-D-CoM were also improved from 0.29/2.34 to 6.33/16.47. In addition, CO2 adsorption over zinc/cobalt azolate frameworks obeyed both Langmuir/Freundlich adsorption isotherm models with good agreements.
