A novel, highly active catalyst Ni@MOF-5 showed unexpected activity at low temperature for CO2 methanation. The characterization results indicated that Ni was uniformly and highly dispersed over MOF-5. This catalyst showed high stability and almost no deactivation in long term stability tests up to 100 h.

Catalyst deactivation causes major losses in the chemical industry worldwide every year [...]

the kinetics of catalyst deactivation and coke formation during dehydrogenation of propane over supported pt–based catalysts and, in particular, the effect of alkali metal promoters on catalyst activity and stability were studied. the analysis of propane conversion data showed that there is an optimum level of alkali metal promoter loading for both catalyst activity and stability.a model based ...

Coking and metal sintering are limitations of large-scale applications Ni/Al2O3 catalysts in DRM reactions. In this review, several modification strategies to enhance the anti-deactivation property proposed discussed with recently developed catalyst systems, including structure morphology control, surface acidity/basicity, interfacial engineering oxygen defects. addition, structure–performance ...
