Methane dry reforming (MDR, CH4 + CO2 → CO + H2) receives great attention because of the contributions to reducing the emission of greenhouse gases and producing valuable syngas. In order to provide a clear sense of the progress of Ni-based catalysts for MDR in recent decades, we summarized the latest related research papers to illustrate new achievements from the aspects of catalyst preparation and molecule activation. First, the reaction patterns and thermodynamics in MDR are briefly introduced. Then, recent advances in design strategy, synthesis approaches, and the MDR mechanism of Ni catalysts are reviewed in detail. Finally, general remarks and perspectives for MDR in the near future are suggested. The challenges of sintering and carbon deposition on the Ni-based catalysts can be alleviated by rational catalyst design and synthesis, and the pathway of MDR can be revealed by mechanism investigation. These strongly support the establishment of a structure–performance relationship for the MDR reaction over the Ni-based catalysts. It is hoped that this paper will give researchers new ideas and guidance for innovation regarding the MDR reaction, especially for designing stable Ni catalysts and studying the MDR mechanism.

“…Ni–Rh bimetallic catalysts supported on mesoporous alumina (MAl) have been reported to improve catalyst activity and high resistance to coking . The heterogeneous bimetallic phase formed by Ni–Rh increased carbon gasification through the hydrogen spillover effect and improved the DRM activity and stability of the catalysts .…”

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.
