“…In all catalysts, the small peak at 430–570°C is the result of NiO phase reduction contacted with the support weakly and the shoulders in bulk catalysts (20Ni/BA and 20Ni‐3Ce/BA) are owing to the strong interaction between NiO phase and Al 2 O 3 support. [ 67 ] The sharp peak at temperatures higher than 700°C is mainly attributed to the formation of NiAl 2 O 4 spinel due to the strong interaction between NiO and Al 2 O 3 . The sharper peak in 20Ni‐3Ce/MA confirms its better reducibility compared with other three samples.…”

Due to the large applications of hydrogen as a feedstock of chemical industries and as an energy carrier, its production on large scales with low costs has attracted researchers. Steam reforming of methane (SRM) is the most common process for producing H2‐rich syngas over Ni/Al2O3 catalysts, which suffer from coke deposition and Ni particles agglomeration. For overcoming these issues, we have synthesized mesoporous alumina (MA) as a supporting material of Ni particles, structure, and activity, which were compared with the bulk alumina (BA) supported catalysts in the SRM process for the first time. Besides, cerium as an appropriate promoter for lowering deposited coke was added to all prepared catalysts. The reaction temperature (600–700°C), Ni loading (10–25 wt.%), and Ce loading (1–5 wt.%) were the parameters that were optimized for maximizing H2 yield and CH4 conversion. Prepared samples were characterized by various techniques before and/or after reaction. The results of TEM and XRD depicted the formation of nanocrystalline and mesoporous structure for Ni‐MA catalysts compare to Ni‐BA samples. The observations indicated that 20Ni‐3Ce/MA had the highest catalytic performance, achieving a CH4 conversion of 91.0% and H2 yield of 92.8% at 700°C.

Transitioning from both the direct and indirect use of fossil fuels to the renewable and sustainable resources of the near future demands a focal shift in catalysis research – from investigating catalytic reactions in isolation to developing coupled reactions for modern chemical value chains. In this Perspective, we discuss the status and emerging prospects of coupled catalytic reactions across various scales and provide key examples. Besides being a sustainable and essential alternative to current fossil‐based processes, the coupling of catalytic reactions offers novel and scalable pathways to value‐added chemicals. By emphasizing the specific requirements and challenges arising from coupled reactions, we aim to identify and underscore research needs that are critical to expedite their development and to fully unlock their potential for chemical and fuel production.
