“…Conversion of CH 4 or CO 2 individually possesses relatively lower activation energy compared with activation of both CH 4 and CO 2 in the same reaction. However, considering methane and carbon dioxide co-exist in natural gas, the conversions of both gases have significant implication toward the utilization of natural gas.…”

“…Methane is the most stable hydrocarbon due to its strong C‐H bond (434 kJ/mol) and thus its activation needs a high temperature. There are various techniques to convert methane to more valuable chemicals and fuels, which can be classified into three types of routes: (1) reforming to produce syngas including steam reforming (Equation ), dry reforming (Equation ), and partial oxidation (Equation ); (2) oxidative coupling (Equation and Equation ); and (3) conversion to oxygenates such as methanol (Equation ).…”

“…Methane is the most stable hydrocarbon due to its strong C-H bond (434 kJ/mol) and thus its activation needs a high temperature. There are various techniques to convert methane to more valuable chemicals and fuels, [1][2][3][4][5] which can be classified into three types of routes [6][7][8] As an indirect approach for highly valuable hydrocarbon production from CH 4 , the first route can be followed by Fischer-Tropsch reaction (Equation 7). Although such a multi-step process has high product yield, the syngas production is expensive due to its high capital costs and it is therefore only economically viable if it is conducted on a large scale.…”

“…(1) CH 4 Carbon dioxide, which is a linear molecule with a C-O bond strength of 532 kJ mol −1 , is very stable. Furthermore, the large positive value (394.6 kJ mol −1 ) of CO 2 formation Gibbs free energy contributes to its high inertness.…”

“…6 Dry reforming of methane yielded a lower syngas ratio (H 2 / CO 1:1) (Equation 2), which is suitable for production of oxygenated chemicals 15 from Fischer-Tropsch synthesis. However, the activation of both C-H bond in CH 4 and C-O bond in CO 2 , which requires efficient catalysts, is a great challenge due to their high stabilities. [16][17][18][19] Catalysts used for DRM can be divided into two groups: earth-abundant transition metals and noble metals.…”

Two typical processes have been developed for the conversion of methane and carbon dioxide to higher valuable products: dry reforming of methane (DRM) and CO2‐oxidative coupling of methane (CO2‐OCM). Numerous articles reviewed progresses in either DRM or CO2‐OCM, but no one covers both processes. In this review article, we systematically evaluated progresses in both DRM and CO2‐OCM processes for conversion of methane and CO2 to highly valuable products. Critical issues, which are carbon deposition and high energy cost for DRM and the contradiction between large activity and high selectivity for CO2‐OCM, were emphasized. Strategies to develop effective catalysts were evaluated, including the enhancement of metal‐support interactions, the introduction of promotors, the formation of solid solutions, and the construction of core‐shell structures. Plasma and photocatalysis were discussed as new promising technologies for DRM and CO2‐OCM.

Methane (CH4) is inexpensive, high in heating value, relatively low in carbon footprint compared to coal, and thus a promising energy resource. However, the locations of natural gas production sites are typically far from industrial areas. Therefore, transportation is needed, which could considerably increase the sale price of natural gas. Thus, the development of distributed, clean, affordable processes for the efficient conversion of CH4 has increasingly attracted people's attention. Among them are plasma technology with the advantages of mild operating conditions, low space need, and quick generation of energetic and chemically active species, which allows the reaction to occur far from the thermodynamic equilibrium and at a reasonable cost. Significant progress in plasma‐assisted reforming of methane (PARM) is achieved and reviewed in this paper from the perspectives of reactor development, thermal and nonthermal PARM routes, and catalysis. The factors affecting the conversion of reactants and the selectivity of products are studied. The findings from the past works and the insight into the existing challenges in this work should benefit the further development of reactors, high‐performance catalysts, and PARM routes.

Steam natural gas reforming is the preferred technique presently used to produce hydrogen. Proposed in 1932, the technique is very well established but still subjected to perfections. Herein, first, the improvements being sought in catalysts and processes are reviewed, and then the advantage of replacing the energy supply from burning fuels with concentrated solar energy is discussed. It is especially this advance that may drastically reduce the economic and environmental cost of hydrogen production. Steam reforming can be easily integrated into concentrated solar with thermal storage for continuous hydrogen production.
