| 英文摘要 | It is attractive but still remains challenging to develop efficient water oxidation electrocatalysts working in a carbonate (Ci) electrolyte. In this communication, we report that a Ni-Co-Ci layer can be developed on a NiCo2O4 nanowire array supported on carbon cloth (NiCo2O4/CC) via electrochemical surface derivation of NiCo2O4. The resulting NiCo2O4@ Ni-Co-Ci core-shell nanowire array on carbon cloth (NiCo2O4@ Ni-Co-Ci/CC) exhibits high activity toward water oxidation in 1.0 M KHCO3 (K-Ci, pH = 8.3) with the over-potential requirement of 309 mV to drive 10 mA cm(-2). NiCo2O4@ Ni-Co-Ci/CC also shows long-term electrochemical stability for 20 h and a high turnover frequency of 0.464 mol O-2 s (1) at an over-potential of 600 mV. |
