Coking and metal sintering are limitations of large-scale applications of Ni/Al2O3 catalysts in DRM reactions. In this review, several modification strategies to enhance the anti-deactivation property of Ni/Al2O3 are proposed and discussed with the recently developed catalyst systems, including structure and morphology control, surface acidity/basicity, interfacial engineering and oxygen defects. In addition, the structure–performance relationship and deactivation/anti-deactivation mechanisms are illustrated in depth, followed by prospects for future work.

Highly dispersed Mn metallic nanoparticles (15.87 nm on average) on a nitrogen-doped porous carbon matrix were prepared by thermal treatment of MnO2-x/polyaniline (PANI), which was derived from the in situ polymerization of aniline monomers initiated by γ-MnO2 nanosheets. Owing to the large surface area (1287 m2/g), abundant active sites, nitrogen dopants and highly dispersed Mn sites on graphitic carbon, an impressive specific capacity of 1319.4 mAh g−1 with an admirable rate performance was delivered in a Li-S battery. After 220 cycles at 1 C, 80.6% of the original capacity was retained, exhibiting a good cycling stability.

Synthesis of well dispersed and strongly interacted Ni-based catalysts benefits the catalytic performances in high-temperature reactions. Significant works have been reported on the roles of calcination environments. During calcination of the catalyst precursors (pretreatment or activation in other cases), the type of atmospheres greatly affects the size, metal-support interaction (MSI) and surface properties of Ni-based catalysts, influencing the catalytic performances. In this review, it is the first time to comprehensively summarize the influences of three categories of atmospheres – oxidative (air, O2 and CO2), inert (N2, Ar) and reductive (H2, NO, N2O and CO) gases, on the physiochemical properties of Ni-based catalysts, which provides a facile and general strategy to optimize the formation of metal nanoparticles on the supports.

A series of LaNi1-xCoxO3 (x = 0, 0.2, 0.5, 0.8 and 1) perovskite catalysts were prepared successfully and applied for toluene steam reforming as a model tar molecule. The Ni–Co alloy formation in reduced LaNi1-xCoxO3 was confirmed by TPR, XRD and XPS. The strong interaction in LaNi0.8Co0.2O3 between Ni and Co produced highly dispersed and smaller metal (8–9 nm), higher reducibility and larger amounts of active sites as well as more abundant oxygen defects and higher surface/lattice oxygen mobility, confirmed by XRD, TEM, TPR, XPS and O2-TPD. Also, a higher electron density prevented Ni from oxidation and sintering; a more oxidized Co (Co3+) facilitated the dissociation of water and activation of CO2, thus removing the coke. At 600 °C, S/C = 3.4 and WHSV = 16.56 ml h−1 gcat−1, an equilibrium conversion was achieved initially and over 80% conversion after 24 h were obtained for LaNi0.8Co0.2O3 with a high H2 yield (81.8% at maximum) and 8.0 of H2/CO ratio. The graphitic/filamentous coke formation was alleviated and no metal sintering was presented after the reaction.

The greenhouse effect is leading to global warming and destruction of the ecological environment. The conversion of carbon dioxide and methane greenhouse gases into valuable substances has attracted scientists’ attentions. Dry reforming of methane (DRM) alleviates environmental problems and converts CO2 and CH4 into valuable chemical substances; however, due to the high energy input to break the strong chemical bonds in CO2 and CH4, non-thermal plasma (NTP) catalyzed DRM has been promising in activating CO2 at ambient conditions, thus greatly lowering the energy input; moreover, the synergistic effect of the catalyst and plasma improves the reaction efficiency. In this review, the recent developments of catalytic DRM in a dielectric barrier discharge (DBD) plasma reactor on Ni-based catalysts are summarized, including the concept, characteristics, generation, and types of NTP used for catalytic DRM and corresponding mechanisms, the synergy and performance of Ni-based catalysts with DBD plasma, the design of DBD reactor and process parameter optimization, and finally current challenges and future prospects are provided.

Dry reforming of methane (DRM) reaction has drawn much interest due to the reduction of greenhouse gases and production of syngas. Coking and sintering have hindered the large-scale operations of Ni-based catalysts in DRM reactions at high temperatures. Smart designs of Ni-based catalysts are comprehensively summarized in fourth aspects: surface regulation, oxygen defects, interfacial engineering, and structural optimization. In each part, details of the designs and anti-deactivation mechanisms are elucidated, followed by a summary of the main points and the recommended strategies to improve the catalytic performance, energy efficiency, and utilization rate.

Nickel-based catalysts are widely used in dry reforming of methane (DRM) due to good catalytic activity and low industrial cost. However, carbon deposition hinders the large-scale applications. In this short review, the applications of perovskites, transition metal oxides, rare earth metal oxide, and mixed oxide materials in DRM are discussed based on the effects of oxygen defects. Also, the formation mechanisms of oxygen defects in nickel-based catalysts are elucidated. It is found that oxygen defects promote the movement of oxygen species and produce more surface oxygen, which effectively reduces carbon deposition in DRM.
