DOI: 10.1002/advs.202207756
Abstract: Metal‐exchanged zeolites are well‐known propane dehydrogenation (PDH) catalysts; however, the structure of the active species remains unresolved. In this review, existing PDH catalysts are first surveyed, and then the current understanding of metal‐exchanged zeolite catalysts… read more here.

DOI: 10.1016/j.fuel.2021.121807
Abstract: Abstract Selective non-catalytic reduction of NOx (SNCR) with NH3 is commonly used in industrial facilities like circulating fluidized bed (CFB) furnaces. However, the strongly temperature-dependent de-NOx feature confines its applications in a specific temperature range… read more here.

Computational Insights into the Mechanism of the Selective Catalytic Reduction of NOx: Fe- versus Cu-Exchanged Zeolite Catalysts
Sign Up to like & getrecommendations! Published in 2019 at "ACS Omega"
DOI: 10.1021/acsomega.9b00600
Abstract: We computationally investigate the mechanism of the reduction half-cycle of the selective catalytic reduction of nitrogen oxides with ammonia. We compare both Fe- and Cu-exchanged zeolite catalysts and aim at exploring all accessible reaction pathways.… read more here.
