What is Microwave-assisted synthesis of well-shaped UiO-66-NH2 with high CO2 adsorption capacity about?
Microwave-assisted synthesis CO 2 capture CO 2 /N 2 separation ## A B S T R A C T In a detailed study, the influence of microwave irradiation, synthesis time and temperature, addition of acetic acid (HAc) as a modulator on the morphology, crystallinity and stability of UiO-66-NH 2 is investigated to develop a reliable and reproducible strategy for the preparation of well-shaped UiO-66-NH 2 . The UiO-66-NH 2 were characterized by powder X-ray diffraction (PXRD), field emission scanning electron microscopy (FESEM), thermogravimetric analysis (TGA), and gas adsorption. It is found that well-shaped UiO-66-NH 2 with a high CO 2 adsorption capacity can be synthesized in a short time by microwave heating. The UiO-66-NH 2 crystals synthesized by microwave heating are of high quality and show a superior CO 2 adsorption capacity (5.8 mmol/g at 273k and 1 bar) due to the strong interactions between the -NH 2 group and CO 2 . The CO 2 /N 2 selectivity of the obtained UiO-66-NH 2 at 298 K and 1 bar is 66, which is much higher than that of the pristine UiO-66 of 17.8.
