The Cover shows that N₂O from plant can be effectively decomposed into N₂ and O₂ over a series of Co-Ti oxides. In their Full Paper, C. Zhang et al. show that deactivation occurred over time for the Co₃O₄ catalyst, however, Co_0.6Ti maintained nearly 100 % N₂O conversion for at least 30 h. Moreover, the Co_0.6Ti catalyst showed much stronger resistance against 1.5 vol. % O₂, 2.4 vol. % H₂O, or 1.6 vol. % NO in the feed compared with the Co₃O₄ catalyst. The existence of a strong interaction between Co and Ti oxides in the Co_xTi catalysts is thought to be the reason, leading to a larger BET specific surface area and better structural stability than the Co₃O₄ catalyst. The deactivation of the Co₃O₄ catalyst is attributed to even weaker structural stability, leading to the decrease in the amount of surface Co³⁺. More information can be found in the Full Paper by C. Zhang et al. on page 2155 in Issue 12, 2016 (DOI: 10.1002/cctc.201600231).
