In this study, large quantities of H2N- UiO-66 were sucessfully prepared by continuous –flow processing under microwave irradation. The precursor solutions were continously transfered by a pump system into the microwave oven, which had set up at a desired temperature (80⁓120oC) and irradation frequency (500 W). The results show that H2N- UiO-66 crystals with nanosacale particles (⁓ 20 nm) were obtained within a very short residence time of 5 ⁓ 10min. Opperating conditions as temperature, reaction time, HCl concentration, and linker ration (Amino terephtalic acid/Terephtalic acid) were strongly influenced on the yield as well as porosity of H2N-UiO-66 product. For toluene adsorption experiment, the obtained results show that the adsorption capacity increased with increase of amino group concentration of linker mixture. The maximum toluene adsorption capacity of 180 mg.g-1 was obtained on H2N-UiO-66 (100%) at 298 K, which was comparable to those of H2N-UiO -66 synthesized by conventional sovothermal approach. |
