| 英文摘要 | The sluggish kinetics of the oxygen evolution reaction (OER) limits the efficiencies of solar-powered electrical-conversion applications, such as water splitting and carbon dioxide reduction. Herein, we rationally designed a metallic nanostructured nickel sulfide/phosphide hybrid (NiSxPy) as an efficient precatalyst for OER, with one-dimensional (1D) nanowires grown on 1D nanorods. The resulting metallic hybrid NiSxPy catalyst can accelerate the electron transfer process and expose abundant in situ-generated NiOOH species during OER (NiSxPy-O). Therefore, NiSxPy-O exhibits a low overpotential of 192 mV (with 100% iR compensation; this value should be 200 mV without compensation) to achieve an O-2 partial current density (j(O2)) of 10 mA cm(-2) and a robust stability over 135 h without obvious degradation. Moreover, a j(O2) of 10 mA cm(-2) at an overpotential of 315 mV (with 100% iR compensation; this value should be 365 mV without compensation) is attained in near-neutral conditions. These results may pave a new way to design metallic precatalysts with 1D/1D hierarchical nanostructures to boost the OER. |
