- ... Trace iron (Fe) has been found to be critical for improving the catalytic activity of heteroatom-doped carbon materials for oxygen reduction reaction (ORR). However, the exact roles played by the trace Fe in the catalysts have not been studied in detail. In this study, nitrogen (N) and sulfur (S) dual-doped carbon nanospheres were synthesized with and without trace Fe addition, named NSFeDC and NS ...
