“…In addition, the reforming reaction requires an adjustment to the H 2 /CO ratio, and the syngas ratio produced by SMR is higher than 2, which is not conducive to FTS. [ 16 ] The reaction speed of the POM process is faster than that of SMR. It is an autothermal process that can be operated under high‐space‐velocity conditions without an external heating source.…”

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.

“…Based on this, the high oxygen mobility exhibited by perovskite-like materials makes them promissory candidates applied in DRM reactions (Bian et al, 2020;Bhattar et al, 2021). Besides, the high-temperature stability of perovskitelike materials further exacerbates their exploitation in DRM reactions (Shi et al, 2021). In general, LaNiO 3 with perovskite's structure is widely studied, which is usually decomposed to the Ni/La 2 O 3 catalyst after H 2 activation or DRM reaction.…”

The rapid economic and societal development have led to unprecedented energy demand and consumption resulting in the harmful emission of pollutants. Hence, the conversion of greenhouse gases into valuable chemicals and fuels has become an urgent challenge for the scientific community. In recent decades, perovskite-type mixed oxide-based catalysts have attracted significant attention as efficient CO2 conversion catalysts due to the characteristics of both reversible oxygen storage capacity and stable structure compared to traditional oxide-supported catalysts. In this review, we hand over a comprehensive overview of the research for CO2 conversion by these emerging perovskite-type mixed oxide-based catalysts. Three main CO2 conversions, namely reverse water gas shift reaction, CO2 methanation, and CO2 reforming of methane have been introduced over perovskite-type mixed oxide-based catalysts and their reaction mechanisms. Different approaches for promoting activity and resisting carbon deposition have also been discussed, involving increased oxygen vacancies, enhanced dispersion of active metal, and fine-tuning strong metal-support interactions. Finally, the current challenges are mooted, and we have proposed future research prospects in this field to inspire more sensational breakthroughs in the material and environment fields.

The dry reforming of methane (DRM) reaction, which converts two greenhouse gases, CO 2 and CH 4 , into valuable syngas, offers a promising route to carbon sequestration. Nibased catalysts have been widely used for DRM due to the high activity, low cost, and high feasibility. Nevertheless, the rapid deactivation of Ni-based catalysts caused by carbon deposition and/or active metal sintering is the main drawback for large-scale application. In addition, its high energy demand poses additional difficulties due to the heat-absorbing nature of the reaction. The design of bimetallic alloy catalysts has been considered as an effective strategy to improve the activity and stability of Ni-based catalysts. This paper reviews recent advances in Ni-based bimetallic catalysts for DRM processes, which mainly focus on the synergistic effects of the two elements, the role of the second metal, and the reaction mechanism induced by different active species. Finally, the outlook for the development of high-performance catalysts for DRM is proposed. The discussions in the present work may provide helpful information to researchers in the CO 2 conversion fields to optimize catalyst design.
