“…In addition, the conversion of methane and selectivity of C 2 products from the Fe©SiO 2 -catalyzed NOCM were significantly promoted by employing a hydrogen-permeable tubular (SrCe 0.7 Zr 0.2 Eu 0.1 O 3−δ ) membrane to separate hydrogen [71]. And more mechanistic and kinetic studies were also conducted to optimize the ideal reaction conditions of Fe 1 ©SiC 2 -catalyzed, direct, non-oxidative coupling of methane to produce C 2 hydrocarbons [79,80]. Furthermore, Fe©CRS is another NOCM catalyst with silica (polymorph cristobalite)-supported active Fe sites synthesized by a similar fusing process [72].…”

Direct upgrading of methane into value-added products is one of the most significant technologies for the effective transformation of hydrocarbon feedstocks in the chemical industry. Both oxidative and non-oxidative methane conversion are broadly useful approaches, though the two reaction pathways are quite distinguished. Oxidative coupling of methane (OCM) has been widely studied, but suffers from the low selectivity to C2 hydrocarbons because of the overoxidation leading to undesired byproducts. Therefore, non-oxidative coupling of methane is a worthy alternative approach to be developed for the efficient, direct utilization of methane. Recently, heterogeneous catalysts comprising singly dispersed metal sites, such as single-atom catalysts (SAC) and surface organometallic catalysts (SOMCat), have been proven to be effectively active for direct coupling of methane to product hydrogen and C2 products. In this context, this review summarizes recent discoveries of these novel catalysts and provides a perspective on promising catalytic processes for methane transformation via non-oxidative coupling.
