has a comparable onset potential and a higher diffusion-limiting current density than the commercial 20 wt% Pt/C catalyst in alkaline electrolyte. The oxygen reduction reaction mechanism catalyzed... depends on the proportion of graphic N rather than the total N content. Key words: oxygen reduction reaction; nitrogen-doped carbon; porous structure; red-blood-cell-like morphology Cite this article......
sol-gel method (5.08 m2/g). The oxygen reduction reaction activity of the oxide in 0.1 mol/L KOH solution was studied using a rotating ring-disk electrode. In the tests, the initial potential of 0.88..., compared with the preparation of LSCF perovskite oxide by the traditional method. Key words: oxygen reduction reaction; electrocatalyst; perovskite; layered structure Cite this article as: XU Wei-lai, XU......

reduction electrocatalysis[3-4]. However, the oxygen reduction proceeds at a very slow kinetic rate in both PEMFC and DMFC. The exchange current density of the oxygen reduction reaction at the Pt... represents oxygen reduction reaction.) The linear voltammograms of five catalysts on rotating glassy carbon disk electrode were obtained in O2-saturated 0.5 mol/L H2SO4 solutions, as shown in Fig.5.......

to the catalytic effect of manganese oxide for OR reaction. Key words: oxygen reduction; manganese oxide; gas diffusion electrode; AC impedance oxygen reduction at teflonbonded carbon electrode ZHOU De-bi(周德璧), L? Xin-kun(吕新坤), LIU Dan-ping(刘丹平) School of Chemistry and Chemical Engineering......
studied. The results show that the reaction rate of the Fe2O3-Cr2O3-NiO system is fast during the initial period (reduction degree, α<38%), and then the rate decreases until the end... promotes the reduction of Cr2O3 at the final stage. Further, during the reduction of Fe2O3-Cr2O3-NiO by carbon, interfacial reaction is the rate-controlling step and g(α)=1-(1-α)0.5 is the reaction......
