Fig. 6. XRD patterns of TiO2 nanofibers prepared from the precursors with different TiO2/polymer yield mass ratios after calcination at (a) 500 °C and (b) 750 °C. Symbols ● – indicate the peaks from anatase and ♦ – from rutile; (c) rutile content and (d) anatase and rutile crystallite size in TiO2 nanofibers after calcination at 500 °C and 750 °C vs. the precursor composition. Dotted lines show general trend.
