论文名称：Enhanced Fe dispersion via “pinning” effect of thiocyanate ion on ferric ion in Fe-N-S-doped catalyst as an excellent oxygen reduction reaction electrode

发表刊物：Journal of Power Sources

摘要：In this study, by using thiocyanate as an iron ion dispersing agent, the pinning effect of thiocyanate ion (SCN−)
enables the high dispersion of Fe3+ in a nitrogen-doped carbon polymer and significantly promotes ORR catalysis in both acidic and alkaline media. It shows 47.3 A g−1 kinetic ORR current density in 0.1 M H2SO4 solution at 0.8 V vs. RHE. In addition, SCN− can dope into the base material and modify the surface of catalysts,
which generates strong cyanide N functional groups. Additionally, it also has a higher BET surface area and more
uniform granularity, which accounts for the enhancement in mass transport.
