- 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.
