This review discusses several modification strategies to enhance the anti-deactivation property of Ni/Al2O3 catalysts in DRM reactions, including structure and morphology control, surface acidity/basicity, interfacial engineering, and oxygen defects. It also illustrates the structure-performance relationship and deactivation/anti-deactivation mechanisms, followed by prospects for future research.
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.
