摘要：

Spectroscopic evidence for an enhanced binding of Nitric Oxide (NO) to metal centers with lower oxidation states (open Cu1+ sites) in Cu-3(btc)(2) (HKUST-1) is presented. The Cu1+ sites created by thermal treatment or X-ray exposure exhibit a preferential adsorption of NO compared to H2O. This phenomenon demonstrates the potential use of MOFs with lower oxidation state metal centers for selective gas separation.
