- Summary: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. - Co-author:Chengyong Shu, Yuanzhen Chen∗, Xiao-Dong Yang, Yan Liu, Shaokun Chong etal.
