Abstract:

The application of electrocatalysts for oxygen reduction reaction in energy storage and conversion has attracted extensive attention.However,the large-scale application of platinum-based catalysts is limited by their high cost,scarce resources and poor stability.Carbon-based non noble metal catalysts are expected to be a substitute for platinum-based catalysts due to their low price,excellent reactivity and strong methanol penetration resistance.At present,the improvement of the oxygen reduction activity of carbon-based catalysts reported in the literature was regulating the electronic structure of active sites,increasing the density and accessibility of active sites,and regulating the interface structure of carbon/metal composites.The research progress of carbon-based oxygen reduction catalysts was reviewed from the following three aspects:nonmetallic elements doped carbon-based catalysts,carbon-based non noble metal single-atom catalysts and carbon-based non noble metal nanoparticles catalysts.The problems and challenges faced by carbon-based catalysts were summarized and pointed out,and the development prospects of the catalyst were prospected.
