Dry reforming of methane(DRM)involves the conversion of carbon dioxide(CO2)and methane(CH4)into syngas(a mixture of hydrogen,H2,and carbon monoxide,CO),which can then be used to produce a wide range of products by means of Fischer-Tropsch synthesis.DRM has gained much attention as a means of mitigating damage from anthropogenic greenhouse gas(GHGs)emissions to the environment and instead utilizing these gases as precursors for value-added chemicals or to synthesize sustainable fuels and chemicals.Carbon deposition or coke formation,a primary cause of catalyst deactivation,has proven to be a major challenge in the development of DRM catalysts.The use of nickel-and cobalt-based cata-lysts has been extensively explored for DRM for their high activity and low cost but suffer from poor sta-bility due to coke formation that has hindered their commercialization.Numerous articles have reviewed the various aspects of catalyst deactivation and strategies for mitigation,but few has focused on the ben-efit of bimetallic catalysts for mitigating coke formation.Bimetallic catalysts,often improve the catalytic stability over their monometallic counterparts due to synergistic effects resulting from two metal-to-metal interactions.This review will cover DRM literature for various bimetallic catalyst systems,includ-ing the effect of supports and promoters,on the mitigation of carbonaceous deactivation.
