Defect-controlled Fe-N-doped carbon nanofiber by ball

Jun 02 2020 · The ball-milling of VGCNF was effective to introduce nitrogen onto the catalyst. In particular the controlled ball-milling was important to generate highly active sites on the catalyst surface. Among the catalysts studied BM2-Fe-VGCNF exhibited the best ORR performance which was 2.5-times greater than that of BMx-Fe-VGCNF (x=4 6). Wi RM 17.2 kWh/t Wi C 17.6 kWh/t The "sick" mill corresponds to the May 2012 survey and the "healthy" mill corresponds to the September 2012 conditions in Figures 7 and 8.
