Dry reforming of methane (DRM) transforms greenhouse gases of CH 4 and CO 2 to syngas of H 2 and CO, which conduces to reducing emissions of the greenhouse gases and producing sustainable energy chemicals. Catalysts with confined structures can actively and stably catalyze DRM owing to their unique properties of the confinement effect, metal−support interaction, size effect, etc. The properties significantly contribute to resolve the problems of metal sintering and carbon deposition in DRM. This review summarizes the latest developments of confined Ni catalysts for DRM in recent years. The synthetic approaches of the confined catalysts are first introduced, followed by the achievements of DRM over Ni@M 1 O x (M 1 O x = SiO 2 , Al 2 O 3 , and ZrO 2 ), Ni@zeolite (zeolite = SBA-15, MCM-41, and ZSM-5), bimetallic Ni−M 2 @SiO 2 (M 2 = Cu, In, and Co), and multifunctional (Ni/M 3 O x )@SiO 2 (M 3 O x = CeO 2 , ZrO 2 , and Mg phyllosilicate). After illustration of the mono-and bifunctional mechanisms, the remarks and perspectives of DRM are proposed in the end. The review will shed light on fabricating other new confined catalysts for DRM and other reactions.

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.

A coupling bimetallic Ni–La/MCM-41 catalyst enhanced by radio frequency (RF) plasma for dry reforming

Abstract: Controlling nickel particle size and inhibiting coke deposition on the supported catalyst was an enormous challenge. To solve this problem, La-doped nickel-based catalysts using MCM-41 as the support were prepared...
