Abstract:
Summary: We demonstrate in this communication that large‐scale coaxial nanocables of polypyrrole (PPy)/TiO 2 can be obtained via three steps: (1) synthesis of TiO 2 nanofibers by electrospinning; (2) physical adsorption Fe 3+ oxidant on the surface of TiO 2 nanofibers; (3) followed by polymerization of pyrrole (from vapor) on the surface of TiO 2 nanofibers. During the synthesis, the PPy formed on TiO 2 nanofibers as a template and formed PPy/TiO 2 coaxial nanocables. TEM image proved that PPy (20 nm thickness) covered the surface of TiO 2 nanofibers. Fourier‐transform infrared (FTIR), X‐ray photoelectron spectra (XPS), and X‐ray diffraction patterns (XRD) characterized the chemical structure of the coaxial nanocables. Surface photovoltage spectroscopy (SPS) revealed the surface properties of the PPy/TiO 2 coaxial nanocables.
