| Popis: | Alloying Pt with 3d transition metals can largely promote the electrocatalytic performances of Pt-based nanocatalysts by downshifting the d-band center of Pt and modulating the electronic structure. Here, PtCo nanowire catalysts are obtained by a simple hydrothermal method. Due to the special one-dimensional (1D) nanowire structure and the strong synergistic effect between Pt and Co, the PtCo nanowire catalysts exhibit high electrocatalytic performances for ethanol oxidation reaction (EOR). The mass activity of optimal Pt1Co1 nanowires is 3.69 times of pure Pt. It also shows excellent durability and stability, which can sustain high activity after operating more than 500 cycles of electrochemical cycling. Our works point out a direction for the development of Pt-based nanomaterials with potential industrial application. |
