In recent decades, rising anthropogenic greenhouse gas emissions (mainly CO2 and CH4 ) have increased alarm due to escalating effects of global warming. The dry carbon dioxide reforming of methane (DRM) reaction is a sustainable way to utilize these notorious greenhouse gases. This paper presents a review of recent progress in the development of nickel-based catalysts for the DRM reaction. The enviable low cost and wide availability of nickel compared with noble metals is the main reason for persistent research efforts in optimizing the synthesis of nickel-based catalysts. Important catalyst features for the rational design of a coke-resistant nickel-based nanocatalyst for the DRM reaction are also discussed. In addition, several innovative developments based on salient features for the stabilization of nickel nanocatalysts through various means (which include functionalization with precursors, synthesis by plasma treatment, stabilization/confinement on mesoporous/microporous/carbon supports, and the formation of metal oxides) are highlighted. The final part of this review covers major issues and proposed improvement strategies pertaining to the rational design of nickel-based catalysts with high activity and stability for the DRM reaction.
近几十年来，人为温室气体排放量不断上升（主要是二氧化碳和甲烷），由于全球变暖的影响不断加剧，这引发了人们的警觉。甲烷干重整（DRM）反应是利用这些臭名昭著的温室气体的一种可持续方式。本文综述了用于DRM反应的镍基催化剂开发的最新进展。与贵金属相比，镍具有令人羡慕的低成本和广泛可用性，这是持续开展研究以优化镍基催化剂合成的主要原因。文中还讨论了合理设计用于DRM反应的抗焦镍基纳米催化剂的重要催化剂特性。此外，还重点介绍了基于显著特征通过各种手段（包括用前驱体进行功能化、通过等离子体处理合成、在介孔/微孔/碳载体上稳定化/限制以及形成金属氧化物）来稳定镍纳米催化剂的若干创新进展。本综述的最后部分涵盖了与合理设计用于DRM反应的高活性和稳定性镍基催化剂相关的主要问题及提出的改进策略。
