“…Copper, nickel, platinum, palladium, and zinc-based catalysts are commonly used for MSR reactions under mild-tohigh-temperature conditions [48]. Steam reforming of methanol using catalysts such as Cu/ZnO/Al 2 O 3 [49], Ni-Cu/Al 2 O 3 [50] at 300 °C, CuCrO 2 -CeO 2 at 400 °C [51], and many more [17,43] are being investigated at temperatures between 250 and 600 °C [52]. NiAl layered double hydroxides (LDHs)derived catalysts between 280 and 390 °C are also reported [53].…”

Green hydrogen is the energy carrier set in the roadmap to achieve the net zero target. However, hydrogen as the future energy vector, either in compressed gaseous form or liquefied form, demands a complete overhaul of storage and transportation infrastructure at a global scale. Methanol is one of the commercially viable hydrogen carriers that can overcome the infrastructure challenges associated with the storage and transportation of hydrogen. As a sustainable hydrogen carrier, methanol must be reformed to hydrogen prior to the point of usage. This review begins with a detailed discussion on thermocatalytic methanol reforming, catalysts, operating conditions, and the associated challenges for both stationary and mobility applications. An in‐depth analysis of the existing commercial methanol reformers available for on‐board and onsite hydrogen generation is also presented. The current state of the research‐level photo‐ and electroreforming as a possible alternative to thermocatalytic reforming is reviewed and concludes with the future prospects for methanol reforming.

“…One of the most well-liked methods for producing hydrogen is the hydrolysis reaction due to its high efficiency [ 3 , 4 ]. Hydrogen storage has occurred in many compounds, such as sodium borohydride [ 5 ], ammonia borane [ 6 ], hydrazine hydrate [ 7 ], water [ 8 ], methanol [ 9 ], and magnesium hydrides [ 10 ]. These compounds have become the most promising for on-site hydrogen production.…”

This study aims to prepare new nanocomposites consisting of Cr2O3/CaCO3 as a catalyst for improved hydrogen production from NaBH4 methanolysis. The new nanocomposite possesses nanoparticles with the compositional formula Cr2−xCaxO3 (x = 0, 0.3, and 0.6). These samples were prepared using the sol-gel method, which comprises gelatin fuel. The structure of the new composites was studied using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, environmental scanning electron microscopy (ESEM), and X-ray spectroscopy (XPS). The XRD data showed the rhombohedral crystallinity of the studied samples, and the average crystal size was 25 nm. The FTIR measurements represented the absorption bands of Cr2O3 and CaO. The ESEM micrographs of the Cr2O3 showed the spherical shape of the Cr2O3 nanoparticles. The XPS measurements proved the desired oxidation states of the Cr2−xCaxO3 nanoparticles. The optical band gap of Cr2O3 is 3.0 eV, and calcium doping causes a reduction to 2.5 and 1.3 eV at 15.0 and 30.0% doping ratios. The methanolysis of NaBH4 involved accelerated H2 production when using Cr2−xCaxO3 as a catalyst. Furthermore, the Cr1.7Ca0.3O3 catalyst had the highest hydrogen generation rate, with a value of 12,750 mL/g/min.

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.
