- In this work, a series of mesoporous carbonaceous materials (MCs), which are simultaneously doped with N and Fe-containing species, were prepared by polymerization of potassium hexacyanoferrate-mediated chitosan on SiO2 nanospheres. The SiO2 template was carbonized and etched with NaOH. The electrochemical properties of the MCs as nonprecious-metal electrocatalysts for oxygen reduction reaction (ORR) are characterized, which was performed using cyclic voltammetry (CV) and linear sweep voltammetry (LSV) employing a rotating disk electrode (RDE). The results show that chitosan with well-dispersed Kªª4Fe(CN)6 nanoparticles prepared by annealing at 800øC (CTS-Fe-800) exhibits the highest catalytic performance in terms of ORR among the catalysts studied, where the onset potential at 0.91V, half-wave potential at 0.82 V and average transferred electron number of 3.49, were achieved in alkaline media.
