“…Moreover, ammonia decomposition is economically more viable than reforming processes, including methanol reforming, 22,23 and hydrogen and N 2 are the only decomposition products, in contrast to the coproduction of CO, CO 2 , and CH 4 from other liquid H 2 carriers. 24,25 Last but not least, this reaction can be carried out at lower temperatures (450°C or below) than reforming processes (above 800°C). 17,26,27 Ammonia decomposition proceeds through stepwise dehydrogenation followed by recombination of two N and two H adatoms to form N 2 and H 2 followed by desorption, and it is thought that NH cleavage is the rate limiting step.…”

“…Nickel (Ni) is commonly used as the metal catalyst in SMR [63][64][65] due to its ability to break the C-C bond. Additionally, Ni is easily reduced and re-oxidized, and offers high conversion efficiency for hydrogen in reforming reactions [66].…”

The high demand for hydrogen has led to the development of various production methods. This study examines the use of synthetic and natural catalysts in the generation of hydrogen and biohydrogen. A bibliographic analysis was conducted using the VOSviewer and ScientoPy tools. The research focuses on hydrogen synthesis, purification, separation, and storage, based on the findings. Hydrogen and biohydrogen can be produced through processes such as reforming, decomposition, hydrolysis, gasification, photolysis, and fermentation. The most studied approach is natural gas steam reforming, using Ni and Ce as catalysts and Al 2 O 3 , Al 2 O 4 , and BaTiO 3 as support materials, resulting in a high turnover frequency (TOF) of 2880 h −1 and an average stability of 100 h. In contrast, ammonia borane (AB) hydrolysis with Pt/Co 3 O 4 catalysts may achieve a high TOF of 15 times faster than steam methane reforming (SMR). Additionally, HY-zeolite containing nickel has a maximum stability of 578 h. Enhancing hydrogen and biohydrogen generation could be achieved by incorporating two or more metals that work synergistically and by building hierarchical structures in zeolite. In photocatalysis, it is important to design catalysts that improve light absorption. Using activated natural zeolites in the gasification process (conventional, supercritical, or hydrothermal) requires various raw materials and advanced chemical processes, which poses challenges for future work.

“…These technologies are required to overcome mass transfer and reaction equilibrium limitations which are frequently encountered. With the use of membranes, it is possible to continuously recover the hydrogen with a high selectivity stimulating a shift of the reaction equilibrium towards a higher hydrogen yield [30][31][32]. Hence, membranes are used to minimize reactor size and eliminate the requirements for hydrogen purification in downstream processes, such as water-gas shift and pressure swing adsorption units [33].…”
