生物质/煤基炭材料作为氧还原反应电催化剂的研究进展OA

The oxygen reduction reaction(ORR)is essential for fuel cells and metal-air batteries,but its slow kinetics and high overpotential restrict battery performance.Traditional platinum-based catalysts are expensive,have limited reserves and exhibit poor stability,hindering large-scale commercialization.This paper reviews recent advances in the research of biomass/coal/-based electrocatalysts for ORR.Covering key aspects such as raw material properties,preparation methods,structural regulation,and practical application cases,this work aims to provide theoretical guidance for developing high-performance,low-cost non-precious metal ORR carbon electrocatalysts.In order to improve the performance of carbon-based ORR electrocatalysts and promote their industrialization,future investigations into guaranteeing raw material homogeneity,precisely regulating of active sites,optimizing structural design,and developing large-scale preparation procedures will serve as the key directions for its further breakthrough in performance and industrialization.
