Figure 2 shows the XRD patterns of the pure TiO2 nanofibers (Fig. 2(a)) and Ag-coated TiO2 (Fig. 2(b)). The XRD pattern of the TiO2 (anatase form, JCPDS 21-1272) had reflections at 2 ∼ 25.3, 37.9, 48.1, 54.2 and 62.8, respectively. The diffraction pattern of the TiO2 prepared by the electrospinnig process showed no peaks of impurity, suggesting that the product consists of a pure phase of material. However, additional peaks at 2 = 44.15 and 64.32 representing Bragg reflections from the (200) and (220) planes of the face-centered cubic (fcc) Ag phase (JCPDS No. 4-0783)22 were seen for the Ag-coated TiO2 nanofiber composites. No other peaks were observed in
the XRD pattern of Ag-coated TiO2. Therefore, we conclude that the Ag-coated TiO2 composite consists of pure Ag and TiO2. High resolution XPS spectra of Ag-coated TiO2 nanocomposite (Fig. 3) exhibit strong bands corresponding to Ag3d3/2and Ag3d5/2 and provide evidence for the existence of Ag nanoparticles in the composite. The photocatalytic activities of the samples were evaluated by the degradation rates of methyl orange under UV-light irradiation. Figure 4 displays the photocatalytic curves of the Ag/TiO2 composites with different silver loadings. The photodegradation efficiency of MO under in the presence of the TiO2 nanofiber was 42% after 3 h of UV-illumination (Fig. 4(a)). The photocalytic performance was clearly significantly enhanced after the coating of silver on the TiO2 nanofibers (Figs. 4(b–d)). The activity increased for composites with silver loadings of 1 and 3 wt%, and then decreased when the silver loading
was increased to 4 wt%. The optimum silver loading for achieving high photocatalytic activity was 3 wt%; about 90% of the dye was degraded after irradiation for only 2 h.
