DOI: 10.1007/s10562-017-2180-8
Abstract: Co3O4 and K/Co3O4 were tested in catalytic N2O decomposition. K/Co3O4 exhibited higher activity than Co3O4, which was drastically and irrecoverably decreased with added NO. Studies revealed that the Co2+ valence state changed after NO adsorption,… read more here.

DOI: 10.1016/j.apcatb.2018.10.068
Abstract: Abstract Four cage-based, small-pore zeolites with similar framework Fe contents (0.7-0.9 wt%) but different framework structures (i.e., Fe-PST-7, Fe-LTA, Fe-SSZ-13, and Fe-RTH) have been synthesized and employed as direct N2O decomposition catalysts. When steam-activated, the light-off… read more here.

Effect of Water Molecule on Photo-Assisted Nitrous Oxide Decomposition over Oxotitanium Porphyrin: A Theoretical Study
Sign Up to like & getrecommendations! Published in 2020 at "Catalysts"
DOI: 10.3390/catal10020157
Abstract: Water vapor has generally been recognized as an inhibitor of catalysts in nitrous oxide (N2O) decomposition because it limits the lifetime of catalytic reactors. Oxygen produced in reactions also deactivates the catalytic performance of bulk… read more here.

DOI: 10.3390/catal10101139
Abstract: Layered 2D zeolite MCM-22 and its delaminated derivative, ITQ-2, were modified with iron, by different methods (ion-exchange and direct synthesis), and with the use of different precursors (FeSO4∙7H2O, Fe(NO3)3∙9H2O, and [Fe3(OCOCH3)7∙OH∙2H2O]NO3 oligocations. The applied modifications… read more here.
