Abstract: A pine-needle-like structure of tungsten oxide (WO3) nanowires on carbon nanofibers was conveniently synthesized from ammonium tungstate (AT) and poly(acrylonitrile-co-methyl acrylate) (P(AN-MA)). Firstly, the solution mixture of AT and P(AN-MA) in dimethylformamide (DMF) was electrospun into smooth composite nanofibers with 300-700 nm diameters. Then AT and P(AN-MA) were simultaneously converted into WO3 and carbon by a heating process. In this process, a pine-needle-like hierarchical structure was surprisingly obtained, with 〈020〉 orienting WO3 nanowires thoroughly covering the amorphous carbon nanofibers. This composite structure has potential applications in a cold cathode, UV detectors, gas sensors and other areas.
