Critical factors such as doping content, electronic conductivity and porosity need to be addressed to obtain excellent oxygen reduction reaction (ORR) performance with metal-free carbon-based materials. However, creating a facile approach to obtain carbon materials with a high doping level, high graphitization degree and high surface area still remains a great challenge. In this work, we develop a NaN3/C5F5N deflagration method to synthesize high N/F co-doped carbon hollow nanospheres (N/F-HC) with a high graphitization degree. The deflagration of NaN3 can produce Na nanoclusters, which can not only capture partial F atoms from C5F5N but can also be used as templates for the formation of a hollow structure. The heat liberation from deflagration and the subsequent F-capturing reaction could generate an extremely high temperature for graphitic structure formation. Moreover, the ultra-fast deflagration and F-capturing reaction allow carbon growth to be completed in seconds, which can ensure a high N/F doping content. The optimized N/F-HC catalyst exhibits superior ORR performance with long-term stability compared to a com. Pt/C electrocatalyst in an alk. medium. The synthetic strategy described in this work is facile and is expected to underpin future research efforts to develop metal-free electrocatalysts for the ORR and other applications. This study involved multiple reactions and reactants, such as 2,3,4,5,6-Perfluoropyridine (cas: 700-16-3Application of 700-16-3).
2,3,4,5,6-Perfluoropyridine (cas: 700-16-3) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.Application of 700-16-3
