CuAlCl4 doped MIL-101 as a high capacity CO adsorbent with selectivity over N2

A CuAlCl 4 doped metal organic framework, CuAlCl 4 @MIL-101, was prepared by introducing CuAlCl 4 into the pores of MIL-101 for the selective adsorption of CO over N 2 . The CuAlCl 4 molecules were evenly distributed into various pores sizes and did not change the intrinsic structure of the MIL-101....

Summary:A CuAlCl 4 doped metal organic framework, CuAlCl 4 @MIL-101, was prepared by introducing CuAlCl 4 into the pores of MIL-101 for the selective adsorption of CO over N 2 . The CuAlCl 4 molecules were evenly distributed into various pores sizes and did not change the intrinsic structure of the MIL-101. Isotherms for CO and N 2 adsorption at 298 K showed that the CO capacity on CuAlCl 4 @MIL-101 was much higher than that on virgin MIL-101, whereas the N 2 capacity decreased. The selectivity for CO over N 2 improved from 4.64 to 31.5 at 298 K and 1 bar. The CuAlCl 4 @MIL-101 adsorbent displayed outstanding CO adsorption stability and the adsorbent could be regenerated by applying a simple vacuum of 4 mmHg.
