Synthesis and characterization of A-MoO3-x/rGO hybrid fiber. (a) Schematic illustration showing the structure evolution of α-MoO3 belts during the preparation of A-MoO3-x/rGO hybrid fibers. (b) SEM (scanning electron microscope) image of A-MoO3-x/rGO hybrid fiber obtained at 6.0 h. (c) Cross-sectional SEM image of the obtained A-MoO3-x/rGO hybrid fiber and the corresponding EDS mapping. (d) Digital photograph of A-MoO3-x/rGO hybrid fiber wounded on a PTFE rod. (e) TEM (transmission electron microscope) image of A-MoO3-x/rGO hybrid fiber at the synthetic time of 6.0 h. The insets are particle size distribution of A-MoO3-x on rGO nanosheets and the local TEM image with higher magnification, respectively. (f–h) HRTEM and the corresponding FFT images of A-MoO3-x/rGO hybrid fiber obtained at 6.0 h.
