A new electrocatalyst Co–N/C complex for oxygen reduction reaction (ORR) was prepared by different cobalt salts using ethylenediamine as a nitrogen source. The Co5.47N/C was prepared by sintering at 1000 °C for 2 h in a hydrogen atmosphere. The Co–Ac–N/C catalyst that prepared by cobalt acetate was the best catalyst for oxygen reduction and the current density of Co–Ac–N/C electrode at 0.75 V (vs...
A new type of composite electrocatalyst was designed and prepared with NiFe layered double hydroxides (LDHs) for oxygen evolution reaction (OER) and CoPc for oxygen reduction reaction (ORR) supported on carbon nanotubes (CNTs). The NiFe LDH–CoPc/CNT composite exhibits higher electrocatalytic activity and stability than the commercial precious metal catalyst Pd/C + Ru/C in 6 M KOH electrolyte. The...
