Highly stable N-containing polymer-based Fe/Nx/C electrocatalyst for alkaline anion exchange membrane fuel cell applications
文献摘要：
A cost-effective electrocatalyst with high activity and stability was developed.The Fe-Nx and pyridinic-N active sites were embedded in nitrogen-doped mesoporous carbon nanomaterial by carbonization at high temperature.The electrocatalyst exhibited excellent electrochemical performance for the oxygen reduction reaction,with high onset potential and half-wave potential values(Eonset = 1.10 V and E1/2 = 0.944 V)than 20 wt％Pt/C catalyst(1.04 and 0.910 V).The mass activity of the Schiff base network(SNW)based SNW-Fe/N/C@800° electrocatalyst(0.64 mA mg-1@1 V)reached about half of the commercial Pt/C electrocatalyst(1.35 mA mg-1@1 V).The electrocatalyst followed the 4-electron transfer mechanism due to very low hydrogen peroxide yield(H2O2＜1.5％)was obtained.In addition,this electrocatalyst with dual active sites showed high stability during cyclic voltammetry and chronoamperometry measurements.More importantly,the electrocatalyst also demonstrated the power density of 266 mW cm-2 in the alkaline anions exchange membrane fuel cell(AEMFC)test,indicating its prospective application for fuel cells.
