Abstract

A CuAlCl₄ doped metal organic framework, CuAlCl₄@MIL-101, was prepared by introducing CuAlCl₄ into the pores of MIL-101 for the selective adsorption of CO over N₂. The CuAlCl₄ molecules were evenly distributed into various pores sizes and did not change the intrinsic structure of the MIL-101. Isotherms for CO and N₂ adsorption at 298 K showed that the CO capacity on CuAlCl₄@MIL-101 was much higher than that on virgin MIL-101, whereas the N₂ capacity decreased. The selectivity for CO over N₂ improved from 4.64 to 31.5 at 298 K and 1 bar. The CuAlCl₄@MIL-101 adsorbent displayed outstanding CO adsorption stability and the adsorbent could be regenerated by applying a simple vacuum of 4 mmHg.
