“…From the H 2 -TPR results they observed that the synergic interaction between the two metals enhanced the reduction degree of NiO, leading to better dispersed nanoparticles that highly improved the CH 4 conversion and the H 2 yield of the reaction. Similar results were obtained in the DR by Pan and co-workers [174] that tested a series of Ni-Pd/SiO 2 catalysts obtained via oleic acid-assisted wet impregnation method. The results demonstrates that the size of the formed Ni-Pd nanoparticles do not change during reaction, highlighting their superior resistance towards sintering phenomena.…”

Clean biogas, produced by anaerobic digestion of biomasses or organic wastes, is one of the most promising substitutes for natural gas. After its purification, it can be valorized through different reforming processes that convert CH4 and CO2 into synthesis gas (a mixture of CO and H2). However, these processes have many issues related to the harsh conditions of reaction used, the high carbon formation rate and the remarkable endothermicity of the reforming reactions. In this context, the use of the appropriate catalyst is of paramount importance to avoid deactivation, to deal with heat issues and mild reaction conditions and to attain an exploitable syngas composition. The development of a catalyst with high activity and stability can be achieved using different active phases, catalytic supports, promoters, preparation methods and catalyst configurations. In this paper, a review of the recent findings in biogas reforming is presented. The different elements that compose the catalytic system are systematically reviewed with particular attention on the new findings that allow to obtain catalysts with high activity, stability, and resistance towards carbon formation.

“…Therefore, the Ni-In/SiO 2 catalyst performed much better anti-coking performance than the Ni/SiO 2 reference catalyst. Pan et al (2020) synthesized mesoporous silica-supported the bimetallic Ni-Pd catalyst for CRM reaction. The results revealed that the presence of Pd was beneficial to increasing the ratio of the surface-active Ni • of the catalyst.…”

CO 2 reforming of methane (CRM) can effectively convert two greenhouse gases (CO 2 and CH 4) into syngas (CO + H 2). This process can achieve the efficient resource utilization of CO 2 and CH 4 and reduce greenhouse gases. Therefore, CRM has been considered as a significantly promising route to solve environmental problems caused by greenhouse effect. Ni-based catalysts have been widely investigated in CRM reactions due to their various advantages, such as high catalytic activity, low price, and abundant reserves. However, Ni-based catalysts usually suffer from rapid deactivation because of thermal sintering of metallic Ni active sites and surface coke deposition, which restricted the industrialization of Ni-based catalysts toward the CRM process. In order to address these challenges, scientists all around the world have devoted great efforts to investigating various influencing factors, such as the option of appropriate supports and promoters and the construction of strong metal-support interaction. Therefore, we carefully summarized recent development in the design and preparation of Ni-based catalysts with advanced catalytic activity and enhanced anti-coke performance toward CRM reactions in this review. Specifically, recent progresses of Ni-based catalysts with different supports, additives, preparation methods, and so on, have been summarized in detail. Furthermore, recent development of reaction mechanism studies over Ni-based catalysts was also covered by this review. Finally, it is prospected that the Ni-based catalyst supported by an ordered mesoporous framework and the combined reforming of methane will become the future development trend.

“…Table 1 shows catalytic activity in terms of H 2 yield for different supported catalyst systems over different reaction conditions. Ceria supported Ni catalyst, SiO 2 supported Ni catalyst, ZrO 2 supported Nickel catalyst and Al 2 O 3 supported Ni catalyst showed H 2 yield 14%, 36%, 43%, and 63% respectively 6,7,11,12 . Promotional addition of modifier strontium (0.75% Sr) in alumina supported Ni catalyst strengthened the metal support interaction and enhanced basicity 13 .…”

Summary Ceria promoted phosphate‐zirconia supported nickel catalyst (10Ni1Ce/PZr; x = 0, 1, 1.5, 2, 2.5, 3, 5 wt%) are prepared and characterized by XRD, SEM, SEM‐EDX, CH4‐TPSR, NH3‐TPD, cyclic H2TPR‐CO2TPD‐H2TPR, and TPH. Ceria addition induces surface reducibility, exposes reduced phases of NiO and Ni2P2O7 as CH4 decomposition sites, and persuades additional CO2 adsorbed species as formate species over the catalyst surface. It also switches mobile oxygen in the lattice and thereafter oxide vacancy is replenished by oxygen from CO2 to a great extent. Altogether, 1 wt% ceria loading (10Ni1Ce/PZr) ensures more than 90% H2 yield (H2/CO = 0.96) whereas 2 wt% ceria loading inputs constancy in catalytic performance up to 440 min TOS. Up to 3 wt% ceria loading, 97% hydrogen yield (H2/CO ~1) is observed. Catalytic performance deteriorated above that 3 wt% ceria loading due to shading the catalytic active site or reoxidation of metallic nickel by excess ceria.
