Thermal Cycling of a MOF-Based NO Disproportionation Catalyst

摘要

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-NO_2 and N_2O. The thermal stability of MFU-4/ 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.
