Confined carbon species play a dual role in the non-oxidative dehydroaromatization of methane over single-atom Mo/ZSM-5 catalysts. In their Communication on page 1016 ff., N. Kosinov, E. J. M. Hensen et al. applied operando spectroscopy, microscopy, and isotope labeling of methane to establish that polyaromatic hydrocarbons, formed in the micropores of the zeolite catalyst, are necessary intermediates for benzene formation. These species lead to catalyst deactivation by agglomeration in heavy deposits that block access to the pores.

在单原子Mo / ZSM-5催化剂上，受限的碳物质在甲烷的非氧化脱氢芳构化中起着双重作用。N. Kosinov，E。J. M. Hensen等人在第1016页及其后的通讯中。应用甲烷的操作光谱，显微镜和同位素标记来确定在沸石催化剂的微孔中形成的多环芳烃是苯形成的必要中间体。这些物质通过在大的沉积物中发生团聚而导致催化剂失活，从而阻碍了孔隙的进入。
