“…Mixtures of acidic-basic oxides were also employed to improve the stability, the hydrogen yield, and the selectivity [55,[61][62][63][64]92]. Additionally, methods for the preparation of supports and catalysts were extensively studied, with the aim of furthering the highest yield of hydrogen [28,59,[61][62][63][64][65][66]75].…”

“…to reduce the harshness of the reaction conditions, and to increase the catalyst stability [29,30,[54][55][56]. To achieve these requirements of Ni-based catalysts, various synthesis methods (a single-step epoxide-driven sol-gel method, nanoparticles encapsulated with multilayered graphene, a single-step evaporation-induced self-assembly (EISA), and co-impregnation of metallic precursors on a xerogel support) have been developed [28,[57][58][59][60][61][62][63][64][65][66]. Moreover, several supports and promoters were synthesized and used to improve the activity and stability of Nibased catalysts in the ESR process [28, 29, 54-56, 59, 61-67].…”

“…Also, the nickel citrate precursor can improve the catalyst stability due to lower coke formation on the catalyst surface [60]. Furthermore, the activity and stability of Ni-based catalysts can be improved by employing nanoparticles encapsulated with multilayered graphene and a sol-gel [28,57,59,61,64,66]. Ni exhibits good dispersion on the multilayered graphene and is protected in the graphene shell [57].…”

“…Apart from the catalytically active metallic sites, supports and promoters play an important role in the ESR process [28, 29, 54-56, 59, 61-68]. The supports not only promote the interaction between the metal catalysts and the supports but also enhance the dispersion of the metal on the support surface [63,66,69]. Both acidic and basic materials were employed as supports [69][70][71][72][73], and mixed oxides were also used to improve the properties of the catalysts [28,55,56,59,62,63,74,75].…”

Ethanol steam reforming (ESR) is one of the potential processes to convert ethanol into valuable products. Hydrogen produced from ESR is considered as green energy for the future and can be an excellent alternative to fossil fuels with the aim of mitigating the greenhouse gas effect. The ESR process has been well studied, using transition metals as catalysts coupled with both acidic and basic oxides as supports. Among various reported transition metals, Ni is an inexpensive material with activity comparable to that of noble metals, showing promising ethanol conversion and hydrogen yields. Additionally, different promoters and supports were utilized to enhance the hydrogen yield and the catalyst stability. This review summarizes and discusses the influences of the supports and promoters of Ni‐based catalysts on the ESR process.

With increasing global emphasis on environmental sustainability, the reliance on traditional energy sources such as coal, natural gas, and oil is encountering significant challenges. H2, known for its high energy content and pollution‐free usage, emerges as a promising alternative. However, despite the great potential of H2, approximately 95% of hydrogen production still depends on non‐renewable resources. Hence, the shift towards producing H2 from renewable sources, particularly through methods like steam reforming of methanol ‐ a renewable resource ‐ represents a beacon of hope for advancing sustainable energy practices. This review comprehensively examines recent advancements in efficient H2 production using Ni‐based catalysts in methanol steam reforming (MSR) and proposes the future prospects. Firstly, the fundamental principles of MSR technology and the significance in clean energy generation are elucidated. Subsequently, the design, synthesis techniques, and optimization strategies for enhancing the catalytic performance of Ni‐based catalysts are discussed. Through the analysis of various catalyst compositions, structural adjustments, surface active sites, and modification methods, the review uncovers effective approaches for boosting the activity and durability of MSR reactions. By offering a comprehensive critical analysis, this review serves as a valuable reference to enhance MSR hydrogen production efficiency and catalyst performance.

Hydrogen as the most promising alternative energy vector to fossil stands out due to its highly energy density and zero pollution. Extending the hydrogen feedstock from hydrocarbons (e. g., methane) to biomass derived oxygen‐containing compounds (CH3OH, C2H5OH etc.) provides the opportunity for low environmental pollution as well as a promising sustainable energy economy. Recently, ethanol with less toxic and high calorific value than traditional fossil energy (coal, oil and natural gas) has garnered significant attention for ethanol steam reforming (ESR) to produce hydrogen, a key component in fuel cell cogeneration system. This paper reviews recent advances on the catalyst developing strategies including structural constitution control, oxide supports modification, surface topography control and bimetallic interactions, and further discusses the catalytic mechanisms, anti‐carbon deposition and sintering resistance strategies on the ethanol steam reforming (ESR) processes. Finally, the challenges and possible strategies for the development of high‐performance catalysts in terms of fundamental research have been discussed.
