Inside Cover: Catalytic Decomposition of N 2 O over Co–Ti Oxide Catalysts: Interaction between Co and Ti Oxide (ChemCatChem 12/2016)

The Cover shows that N 2 O from plant can be effectively decomposed into N 2 and O 2 over a series of Co‐Ti oxides. In their Full Paper, C. Zhang et al. show that deactivation occurred over time for the Co 3 O 4 catalyst, however, Co 0.6 Ti maintained nearly 100 % N 2 O conversion for at least 30 h. Moreover, the Co 0.6 Ti catalyst showed much stronger resistance against 1.5 vol. % O 2 , 2.4 vol. % H 2 O, or 1.6 vol. % NO in the feed compared with the Co 3 O 4 catalyst. The existence of a strong interaction between Co and Ti oxides in the Co x Ti catalysts is thought to be the reason, leading to a larger BET specific surface area and better structural stability than the Co 3 O 4 catalyst. The deactivation of the Co 3 O 4 catalyst is attributed to even weaker structural stability, leading to the decrease in the amount of surface Co 3+ .
