The possibility of CO2 recycling into standard refinery can largely mitigate greenhouse gas emissions. It was previously demonstrated that alumina modified by either potassium or lithium in the presence of vanadium was able to promote the reaction of CO2 with coke in the presence of O2 during the regeneration step of a spent catalyst. Herein, vanadium‐sodium and vanadium‐calcium on alumina were used to achieve that reaction. These catalysts showed slightly lower conversion compared to previously catalysts. However, regardless of the type of group I and II elements, all catalysts showed very similar apparent activation energy (Eaapp) for the coke oxidation with CO2 reaction (CO2+coketo2.6pc→EaappCO+coke−O), i.e., in the range of 188–193 kJ.mol−1. In contrast without vanadium, Eaapp was in the range of 242–253 kJ.mol−1. Therefore, CO2 is activated in a site composed of V‐O‐(group I or II) in the coke proximity. Moreover, these results clearly support that vanadium plays the main role in the type of activation complex, independently of the group I and II metal used and most probably in the dissociative step of CO2. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…Among the possible technologies to valorize CO 2 , the Boudouard reaction in which CO 2 reacts with carbon to produce carbon monoxide [3] and the dry reforming of hydrocarbons by thermal catalysis have been largely studied [4]. As an alternative to conventional catalytic dry reforming reaction, non-thermal plasma appears as an interesting technology since highly energetic electrons generated by plasma at room temperature are able to initiate chemical processes.…”

In this study, redox exsolution method was used to synthesize Co/Co−Al spinel for dry reforming. The aim is to improve metal‐support interaction, which enhances the catalyst's stability and minimizes carbon deposition. The synthesized catalysts were observed as Co embedded on Co deficient CoAl2O4‐like spinel (denoted as Co−Al spinel). The reduction temperature was optimized at 750 °C. Investigations on the effect of Co loading revealed that optimum Co loading is needed to control the Co particle size, providing balance between limiting carbon deposition rate and preventing dissolution of Co into the support. The best performing catalyst, Co‐15, in which the molar ratio of Co and Al is 15 : 85 produced a stable 81.5 % and 87.4 % conversions for CH4 and CO2 continuously over 24 h of reaction time with 13.51 wt% of carbon deposition. The strong metal‐support interaction of Co and Co−Al spinel in Co‐15 stabilizes and prevents the sintering of Co particles, enhancing the efficiency for dry reforming reaction.
