“…Results are plotted on the basis of methane conversion adopted from Urdiana et al [79] Fig. 3 Comparison of different silica materials as a catalyst support in terms of hydrogen yield from methane decomposition [49] rapidly dropped due to the accumulation of carbon caused by the considerable Ni species on the catalyst surface. The high activity of the catalyst may be due to the synergistic effect of the surface of zeolite and active Ni species.…”

“…Carbon formation may be in the form of carbon black, CNTs [94,96], graphite [143], and graphene [62]. The formation of filamentous carbon as a product can contribute to the stability of catalysts [49,140]. Majewska and Michalkiewucz [136] indicated that a high concentration of metal catalyst (32 wt% Co) produces a high yield of carbon formed at the end of the reaction.…”

The production of hydrogen to be used as an alternative renewable energy has been widely explored. Among various methods for producing hydrogen from hydrocarbons, methane decomposition is suitable for generating hydrogen with zero greenhouse gas emissions. The use of high temperatures as a result of strong carbon and hydrogen (C–H) bonds may be reduced by utilizing a suitable catalyst with appropriate catalyst support. Catalysts based on transition metals are preferable in terms of their activeness, handling, and low cost in comparison with noble metals. Further development of catalysts in methane decomposition has been investigated. In this review, the recent progress on methane decomposition in terms of catalytic materials, preparation method, the physicochemical properties of the catalysts and their performance in methane decomposition were presented. The formation of carbon as part of the reaction was also discussed.Graphic abstract

The hydrogen economy will play a key role in future energy systems. Several thermal and catalytic methods for hydrogen production have been presented. In this review, methane thermocatalytic and thermal decomposition into hydrogen gas and solid carbon are considered. These processes, known as the thermal decomposition of methane (TDM) and thermocatalytic decomposition (TCD) of methane, respectively, appear to have the greatest potential for hydrogen production. In particular, the focus is on the different types and properties of carbons formed during the decomposition processes. The applications for carbons are also investigated.

Research on high‐surface‐area supports and synergic promoters has been made, however, there is still much room for improvement on the catalytic‐particles morphology and interaction with the support. A first approach for designing nanoplate supports to improve CDM catalysts was made. Amorphous aluminosilicates nanoplates (a‐AS.np) with an average particle size of 23.4 nm and an average height of 2.8 nm, and α‐Ni(OH)2 nanoplates (Ni.np) with an average particle size of 23.2 nm and an average thickness of 8.4 nm, were successfully synthesized, using a two‐dimensional reactor in amphiphilic phases (TRAP). Nickel loaded in a‐AS materials with different morphologies and promotion effects of lantana (La3+) & chromium (Cr3+) species were studied. La‐Cr promoted a‐AS support showed an average increase of 13% on H2 yield in severe conditions due to improved crystallization of Ni particles on mesoporous support and the electron promotion of La to Ni species. Furthermore, we evaluate the Ni.np as novel morphology support for La3+ & copper (Cu2+) species in the methane decomposition reaction. La‐Cu Ni.np showed outstanding performance and stability, a max H2 yield of 15.9% (at 700 °C), and more than 400 min of H2 generation (at 550 °C) compared to its a‐AS support counterparts.
