dc.description.abstract | Development of the low-cost, high-efficiency, and durable non-precious metal electrocatalysts for cathodic oxygen reduction reaction (ORR) is of vital importance for fuel cells and metal-air batteries. Herein, the carboncoated NbC nanoparticles (NbC@C NPs) were prepared using DC arc discharge plasma under a methane atmosphere. Then, the nitrogen-doping was conducted by heat treatment, resulting in nitrogen-doped carboncoated NbC nanoparticles (NbC@C(Nx) NPs). Benefiting from the merit of unique core-shell structure and best synergy between the nitrogen-doped carbon shell and the NbC core, the obtained highest nitrogen-doped NbC@C (N-1.36) NPs showed an onset potential (E-onset) of 0.89 V (vs. RHE) and a half-wave potential (E-1/2) of 0.79 V, which are comparable to those of commercial Pt/C (20 wt%) (E-onset = 0.90 V, E-1/2 = 0.80 V), and its diffusion-limited current density (J(L)) of 5.99 mA.cm(-2) is even higher than that of commercial Pt/C (5.43 mA.cm(-2)). Moreover, it exhibited a remarkable long-term durability and impressive methanol resistance than Pt/C catalyst. In addition, the real-time optical emission spectrum (OES) analysis of arc plasma shows that the electron temperature (T-e) is 7562.9 K in local thermal equilibrium (LTE) plasma. Therefore, the use of the DC arc discharge plasma method opens a fast and simple way to develop cost-effective and highly efficient non-precious metal catalysts for ORR. | - |
