Progress on current-responsive catalysts and their applications in intensifying typical reactions
Current-responsive catalysts are a novel type of catalytic materials that can generate electric current under the induced effect of electric field,and the reactions catalyzed by this kind of catalysts can break through the thermodynamic limitation and occur under mild conditions,with significant energy-saving and carbon-reducing potentials.In this article,we reviewed the research progress of current-responsive catalysts intensifying ammonia synthesis,high-value utilization of methane and propane dehydrogenation in recent years.Series of current-responsive catalysts were summarized,which were mainly loaded metal catalysts,consisting of the carrier(semiconductor-type or perovskite-type metal oxides)and active metals(single metal or alloys).The catalytic performance of various catalysts was compared,and the role of"proton hopping"in intensifying corresponding reactions was analyzed.Finally,the future development directions and challenges of current-enhanced technology were prospected.It was proposed that the development of in-situ characterization technology and molecular simulation methods is of great significance for revealing the reaction mechanism from the microscopic level,which can provide guidance for the design of more efficient catalysts,promote the development of related fields,and assist the low-carbon upgrading of the chemical industry.
