Improving the synthesis process of chromium benzenedicarboxylate, MIL-101(Cr), by a microwave pre-step for CO2 adsorption
The primary objective of the present study is to compare the result of adding a microwave-heating pre-step (MW) to the conventional electrical heating method (CE) to synthesize chromium benzenedicarboxylate, MIL-101(Cr), for CO 2 adsorption applications. The results show that using conventional CE t...

adsorption applications. The results show that using conventional CE the time required to complete the synthesis reaction is 24 h while adding a short-period MW to CE as a pre-step can reduce this time to 5 h. The MW pre-step can be carried out under either autogenous pressure or atmospheric condition. The results also revealed that both methods are capable of producing MIL-101(Cr); however, CE method can produce the adsorbent with the CO

adsorption capacity 7.7 mmol/g at 5.0 bar and 25˚C, while the adsorbent synthesized using hybrid method can possess the adsorption capacity 6.1 mmol/g at the same condition. |
