Patent number: 11724248Abstract: The present disclosure relates to copper-containing molecular sieve catalysts that are highly suitable for the treatment of exhaust containing NOx pollutants. The copper-containing molecular sieve catalysts contain ion-exchanged copper as Cu+2 and Cu(OH)+1, and DRIFT spectroscopy of the catalyst exhibits perturbed T-O-T vibrational peaks corresponding to the Cu+2 and Cu(OH)+1. In spectra taken of the catalytic materials, a ratio of the Cu+2 to the Cu(OH)+1 peak integration areas preferably can be ?1. The copper-containing molecular sieve catalysts are aging stable such that the peak integration area percentage of the Cu+2 peak (area Cu+2/(area Cu+2+area Cu(OH)+1)) increases by ?20% upon aging at 800° C. for 16 hours in the presence of 10% H2O/air, compared to the fresh state.Type: GrantFiled: March 19, 2021Date of Patent: August 15, 2023Assignee: BASF CorporationInventors: Wen-Mei Xue, Xiaofan Yang, Haiyang Zhu, Stanley Roth, Jeff Yang, Subramanian Prasad, Ahmad Moini
