Figure 3From: The effects of atmosphere and calcined temperature on photocatalytic activity of TiO2 nanofibers prepared by electrospinningSEM images of heat-treated electrospun fibers under different conditions. (A) 550°C, N2; (B) 550°C, NH3; (C) 600°C, N2; (D) 600°C, NH3; (E) 650°C, N2; and (F) 650°C, NH3. The EDS of heat-treated fibers at 550°C in NH3(G) show the composite fibers without calcination.Back to article page
