“…Recently, some researchers have already started the studies in fields of light, microwave, electricity, etc. for supported catalysts, ,,,− but the related studies for confined catalysts are rare. Considering the stricter physical and chemical confinement effects in the confined catalysts, Ni sintering and carbon deposition may be more alleviated under fields of light, microwave, and electricity for DRM.…”

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.

“…The catalyst deactivation in DRM is mainly caused by carbon deposition, metal sintering, and poisoning. − The coke formation easily covers the metal sites and support pores, preventing the interaction between the reactants and catalysts . Two reactions are responsible for carbon formation: CH 4 cracking (eq ) and CO disproportionation (Boudouard reaction) (eq ).…”

Dry reforming of methane (DRM) is a promising way of transforming greenhouse gases into syngas products and value-added chemicals. Owing to their strong CO 2 adsorption, ordered pore structure, and high surface area, zeolites have been widely applied as the catalyst or the support of catalysts for DRM. In this review, the synthesis and modification strategies of zeolites are comprehensively summarized. Besides, the structure−performance relationship is elucidated by referring to the compositional/physicochemical properties of zeolites and catalytic performances in DRM. In addition, zeolite crystal structures are introduced in classification, and the impacts of reaction parameters on the activity/stability are discussed in detail. Lastly, conclusive remarks and prospects are proposed for reference.

Photothermocatalytic dry reforming of methane (DRM) offers a promising strategy for converting solar energy into fuel. However, the high light intensity required for high fuel production rates and thermodynamically more favorable coking side reactions limit this strategy. Herein, a nanocomposite of La‐doped Al2O3 supporting Ru nanoparticles (NPs) (Ru/La‐Al2O3) is synthesized. At relatively low light intensity (80.2 kW m−2), Ru/La‐Al2O3 obtains high production rates of CO and H2 per gram of Ru (rRu, CO and rRu, H2, 8410.19 and 7181.94 mmol gRu−1 min−1) with light‐to‐fuel efficiency (η, 26.6%), and completely prohibits coking. In striking contrast, the reference catalyst without La doping (Ru/Al2O3) exhibits lower rRu, CO, rRu, H2, η and produces large amounts of coke. The improved photothermocatalytic performance stems from the fact that reactive oxygen species and carbonate species are involved in the oxidation of carbon species (rate‐determining steps of DRM) through two different reaction pathways, which significantly increases catalytic activity and prevents the carbon species from polymerizing into coke. Additionally, light not only enhances the DRM on Ru NPs and the oxidation reaction between carbonate species and carbon species but also promotes the dissociation of CH4 and desorption of H2, which improves the catalytic activity and product selectivity of Ru/La‐Al2O3.
