Enhanced electrocatalytic performance of N-doped carbon xerogels obtained through dual nitrogen doping for the oxygen reduction reaction

Abstract

This work presents a novel tactic to regulate the microstructure and composition of carbon-based catalysts by the facile and scalable dual-effect nitrogen doping method which may be conducive to promoting highly efficient electrocatalysts for ORR.

The simple construction of rice-husk-derived carbon catalyst for oxygen reduction reaction by the synergism of iron and nitrogen co-doping

“…[3][4][5] Carbon with special structures and morphology can be used as the carbon sources in catalyst synthesis, such as graphene, 7,12 carbon nanotubes [13][14][15] and synthetic organics-derived carbon. [16][17][18][19][20] Nevertheless, the tedious preparation steps and high synthesis cost greatly hinder the large-scale application of metal nitrogen co-doped carbonbased catalysts. Considering the wide applications of fuel cells, the use of low-cost renewable carbon precursors to produce carbon-based electrocatalysts is most cost-effective and meaningful from an economic, environmental and ecological point of view.…”
