Recent progress in pyrolyzed carbon materials as electrocatalysts for oxygen reduction reaction

Abstract

Oxygen reduction reaction(ORR) is an important reaction in fuel cells. The efficiency of ORR is related to the efficiency of fuel cells. Therefore, research on ORR catalysts is an important issue. Non-precious metal catalysts(NPMCs) are a research hotspot in recent years due to cost considerations, and carbon-based catalysts are an important component of NPMCs. Carbon-based catalysts have the advantages of wide range of sources, low cost, superior performance and good stability. In this review, the pyrolysis step in the preparation of carbon-based catalysts was used to analyze the composition of the pyrolysis precursor and the effect of the structure on the catalytic activity of the catalyst. We classify carbon-based catalysts into four types according to the type of precursor: biomass-derived, organic mixture-derived, MOF-derived, molded carbon material-derived carbon-based catalyst. At the same time, the influence of pyrolysis conditions on the catalytic activity of the product was discussed.
