Thermal Cycling of a MOF-Based NO Disproportionation Catalyst

Abstract

The metal–organic framework Cu^I-MFU-4l reacts with NO, initially forming a copper(I)-nitrosyl at low pressure, and subsequently generates NO disproportionation products Cu^II–NO₂ and N₂O. The thermal stability of MFU-4l allows NO_x to be released from the framework at temperatures greater than 200 °C. This treatment regenerates the original Cu^I-MFU-4l, which can engage in subsequent cycles of NO disproportionation.
