From: Highly conductive nano-sized Magnéli phases titanium oxide (TiOx)
(a) Fraction of Ti3+ and Ti4+ in the samples based on XAFS analysis. The Magnéli phase composition of each sample was determined based on the XRD spectra of (b) TiOx-A, (c) TiOx-B, and (d) TiOx-C. (i) is the spectra of as-synthesized nanoparticles and (ii) is the spectra of heat-treated nanoparticles.
