Because of the recent global warming environmental issues, dry reforming of methane (DRM)which converts greenhouse gases (CO2 and CH4) into syngases (CO and H2)is receiving significant attention. Recently, density functional theory (DFT) calculations have been effectively used to obtain fundamental information on DRM reactions. The DFT calculations can provide valuable theoretical knowledge in various heterogeneous catalyst systems, which is difficult to derive from experiments alone due to the complexity of reaction pathways. This work introduces theoretical studies concerning the most plausible reaction pathways, catalytic activities, and stabilities of Ni- and non-Ni-based metal catalysts. The review includes fundamental analyses of reaction mechanisms, catalytic activities, and several strategies to improve the catalytic properties of Ni- and non-Ni-based catalysts. Such strategies include doping, introducing promoters, forming bimetallics, and utilizing various catalyst supports. In addition, DFT-based descriptors provide guidelines for DRM catalyst design in terms of activity and stability. In conclusion, this review also suggests DFT-based analyses of catalysts based on morphological and compositional engineering, such as core–shell nanoparticles, single-atom catalysts, phosphides, and reduced solid solution catalysts. Finally, this review suggests a rational catalyst design for DRM by tuning catalytic properties based on engineered catalyst characteristics under a comprehensive understanding provided by DFT calculations and experiments.

“…The performance of a catalyst largely depends on the structural and geometric parameters of the surface (Monteiro et al, 2019;Kopac et al, 2020;Riani et al, 2021). Apart from the traditionally supported catalysts, a class of crystalline oxide catalysts has attracted extensive attention due to their excellent thermal stability (Godding et al, 2019;Koch et al, 2020).…”

“…The conversion of CH 4 and CO 2 to syngas (H 2 + CO) has plentiful applications in synthetic chemistry (Li et al, 2021). Therefore, CO 2 reforming of CH 4 can not only alleviate global environmental problems but also provide a valuable chemical feedstock (Monteiro et al, 2019). It has been proved that the reserves of combustible ice (Gas Hydrate/Natural Gas Hydrate) in the South China Sea are as high as about 200 million cubic meters, equivalent to eight million tons of oil.…”

“…Typically, CH 4 is activated on metals such as Rh, Pt, and Ni to produce carbon, CH x, or formyl intermediates, while CO 2 is activated at the support or interface of the catalyst to form carbonate precursors (Wang et al, 2016;Li et al, 2021). During the DRM reaction, the reduction of CO 2 to CO is accompanied by the generation of oxygen-containing species (or oxygen vacancies) and the enhancement of oxygen mobility, which is beneficial to the oxidation of surface carbon formed by CH 4 activation, thereby eliminating carbon deposition (Monteiro et al, 2019). 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).…”

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.
