One-dimensional nanostructures have unique properties and potential applications, and doping nonmetal elements in metal nanostructures can enhance electrocatalytic reactions. In this study, phosphorus-doped Pt nanowires were successfully synthesized using phosphorization treatment. The results showed that phosphorus doping effectively tuned the electronic structure of Pt nanowires and enhanced their catalytic activity.
One-dimensional nanostructures have drawn substantial attention because of their unique properties and potential applications. Furthermore, doping nonmetal elements in metal nanostructures also exhibits great potential for enhancing various electrocatalytic reactions. Doping nonmetal elements without affecting the morphology of nanostructure is difficult. Using phosphorization treatment on presynthesized Pt nanowires (NWs), we effectively synthesize phosphorus-doped Pt NWs (Pt-P NWs). In the electrochemical hydrogen evolution and methanol oxidation reaction, the prepared Pt-P NWs demonstrated the highest catalytic activities compared with Pt NWs and commercial Pt/C. These results demonstrate that phosphorus doping effectively tuned the electronic structure of Pt NWs that enhance the intrinsic activity.
