Research Progress of Ni-based Composite Catalysts for Methane Dry Reforming

Methane Dry Reforming (DRM) catalysis converts the two greenhouse gases, CO 2 and CH 4 into syngas, which can be further utilized for liquid fuels production through Fischer-Tropsch synthesis.The DRM reaction is therefore of significance for both energy and environments.The key issue to promote industrialization of DRM reaction is to develop suitable catalysts.Nickel based composite catalysts have received extensive attention due to their outstanding catalytic activities comparable to those of precious metals and their bargain price.However, nickel based catalysts usually undergo severe deactivation due to the coke deposition and metal sintering during long-term reaction at high temperature, which seriously limit their industrial applications and development of the engineering of DRM.Many researches have been carried out to address this issue.In this review, the recent research progress in the activity, coke resistance, and sintering resistance of Ni-based composite catalysts are introduced from the aspect of catalyst components, structures, preparation methods, and simulations.The research trends of DRM catalysts are also predicted based on the recent research progress in single-atomic catalysis and the in-situ characterization techniques for catalysis.
