DFT calculations showed5-8 that the high activity of Cu+ in CuZSM-5 could be related to the high energy of the HOMO orbital of Cu+ in MFI and to the ð-back-donation of electrons from the d orbitals of Cu to ð* antibonding orbitals of NO,resulting in a distinct weakening and dissociation of the NdO bond.
