Planar and stepped nickel surfaces are go-to catalysts used industrially in the aforementioned processes, primarily because Ni is procured at cheap rates and portrays excellent reactivity towards methane. The drawback of Ni catalysts is that they can completely dehydrogenate methane into carbon and hydrogen, which causes coking. Nullifying or preventing coking in methane conversion reactions is challenging area of current research. The literature cites multiple studies in both theoretical and experimental verticals across various catalyst classes discussing methane activation. For example, it has been investigated on supported metal clusters, noble metal surfaces, 69 mixed-metal alloys, zeolites, metalorganic frameworks(MOFs), metal oxides, 1315 perovskite, and supported single-atom catalysts (SACs) to name a few. Lately, SACs have emerged as a focal point in active research surrounding methane activation. Doping the base metal with a single atom increases the number of active sites on the surface, thus reducing the use of precious metals as traditional catalysts. SACs, as an interesting class of catalyst subtly modify the electronic structure of the base metal and the dopant itself. This unique alteration of properties is a consequence of changing the atomic environment and dopant-doped interaction.
