“…To enhance the activity of Ni-based catalysts, a common strategy is to support Ni active components on advanced supports with high specific surface area and high stability, supports of interest include Al 2 O 3 , [272,337] La 2 O 3 , [338] CeO 2 , [339] ZrO 2 , [340] MgO, [341] SiO 2 , [263] and molecular sieves. [342] In most cases, the introduction of Ni-based catalysts in PARM systems can significantly improve the conversion of reactants. For example, Wang et al [343] studied the Ni/𝛾-Al 2 O 3 in DBD plasma for PADRM.…”

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.

“…The product obtained from the plasma DRM reaction mainly contains syngas (H 2 /CO), as well as hydrocarbons and oxygenates [8][9][10][11][12][13]. Extensive investigation for plasma-based DRM has been done with various types of plasma technologies, such as dielectric barrier discharge (DBD) [10,[14][15][16][17][18][19], radio-frequency (RF) discharges [20][21][22], glow discharges [13,23], microwave (MW) discharges [24][25][26][27], corona discharges [28,29], and gliding arc (GA) discharges [8,[30][31][32][33][34][35]. It is worth to note that the GA plasma is a promising plasma type for DRM, as it can generate electrons with an energy of around 1 eV, which is ideal for the CO 2 vibrational excitation during the dissociation process [31,36,37].…”
