| 英文摘要 | Engineering the internal structure and chemical composition of nanomaterials in a cost-effective way has been challenging, especially for enhancing their performance for a given application. Herein, we report a general strategy to fabricate hollow nanostructures of ruthenium-based binary or ternary oxides via a galvanic replacement process together with a subsequent thermal treatment. In particular, the as-prepared NiO-RuO_2 hollow nanostructures loaded on carbon nanotubes (hNiO-RuO_2/CNT) with RuO_2 mass ratio at 19.6% for a supercapacitor adopting the KOH electrolyte exhibit high specific capacitances of 740 F g~(–1) at a constant current density of 1 A g~(–1) with good cycle stability. The specific capacitance for hNiO-RuO_2/CNT electrodes maintains 638.4 F g–1 at a current density of 5 A g~(–1). This simple approach may shed some light on the way for making a wide range of metal oxides with tunable nanostructures and compositions for a variety of applications. |
