“…Catalyst performance is directly affected by the synthesis method, and the dispersion of metal particles on the support, particle size, and type of MSI considerably depend on the synthesis method. Synthesis methods that can produce an active and a stable Ni‐based catalyst for the CMD reaction include impregnation, 19,21‐23,60,77‐80,84,96,100,101,103,104,109‐111,114,127‐130 precipitation, 76,87,95,105,112,131‐134 and the sol‐gel method 67,68,94,97,108,116 . In addition, polyol reduction, 113,118,135 EISA, 85,115 fusion, 82 and emulsion 136 are employed.…”

Summary Hydrogen is a clean energy medium that can potentially replace fossil fuels in home, industrial, and transportation environments. Nonoxidative catalytic methane decomposition (CMD) is an environmentally friendly process that produces hydrogen and solid carbon as products. Among transition metal catalysts, Ni possesses a high degree of activity for methane decomposition. This article reviews the recent advancement (ie, 2015‐2020) of a Ni‐based catalyst for CMD and summarizes its performance. It addresses the effect of promoter, metal composition, support materials selection, catalyst synthesis, operating parameters, and reaction mechanism. Besides, other critical aspects for industrial application of CMD such as reactor design and catalyst regeneration are highlighted. Novelty Statement Catalytic methane decomposition is a promising technology for the co‐production of COx‐free hydrogen and carbon nanomaterials. The Ni‐based catalyst possesses a high degree of activity for catalytic methane decomposition. Regeneration by gasification should be considered to extend the operational life of the Ni‐based catalyst. A fluidized bed reactor is a suitable reactor type for the practical application of catalytic methane decomposition.

“…In the case of metal catalysts, the carbon produced covers the active sites, causing the rapid deactivation of catalysts and, thus, shortening their lifetime. In addition to this, the sintering of particles occurs at high temperatures and contributes to the activity loss of metal catalysts [60,63,83,91,108,[139][140][141][142][143][144][145][146]. Carbon materials also deactivate faster at higher temperatures.…”

The Carbon2Chem® project aims to convert exhaust gases from the steel industry into chemicals such as methanol to reduce CO2 emissions. Here, H2 is required for the conversion of CO2 into methanol. Although much effort is put to produce H2 from renewables, the use of fossil fuels, especially natural gas, seems to be fundamental in the short term. For this reason, the development of clean technologies for the processing of natural gas with a low environmental impact has become a topic of utmost importance. In this context, methane pyrolysis has received special attention to produce CO2‐free H2.

“…There are many applications of SBA‐15 in the production of hydrogen from methane decomposition and waste plastics gasification. Urdiana et al 33 synthesized nickel, copper, cobalt, manganese, iron, zinc and tungsten single‐metal catalysts using an impregnation method with SBA‐15 as a support. During methane pyrolysis, the methane conversion was found to be 40% when using Ni/SBA‐15 as the catalyst.…”

Hydrogen is considered an ideal energy carrier. However, the use of fossil fuels to produce hydrogen depletes natural resources and causes environmental problems. Therefore, there is an urgent need to find alternative raw materials and technologies for the production of hydrogen. Waste cooking oil (WCO) is a renewable energy source that has emerged as a potential raw material for hydrogen production. This study describes the production of hydrogen and carbon nanotubes (CNTs) by catalytic cracking of a WCO model compound (WCOMC) performed in a lab-scale fixed bed using Ni-Co/SBA-15 catalysts. The phase, structure and reduction properties of the catalyst were analysed by using different characterisation methods. The effects of the nickel-cobalt metal content and the reaction temperature on both the hydrogen production and the quality of the CNTs were investigated. The deposited carbonaceous products were characterised to analyse their external appearance, internal structure, oxidation stability and graphitisation degree. The results indicated that the catalyst containing 20% Ni and 30% Co showed the highest activity. When reaction temperature was 800 C, the instantaneous volume fraction of hydrogen was close to 43.5 vol% and the content of hydrogen in the gas product was close to 66.5 vol%. A few multi-walled CNTs having a small diameter and some CNTs with an open-topped structure were deposited on 10%Ni-40%Co/SBA-15 and 30%Ni-20%Co/SBA-15, respectively. Thermogravimetric analysis and Raman spectroscopic analysis indicated that all CNTs showed high oxidation stability and a high degree of graphitisation.
