XRD analysis of the initial β Fe2O3 sample

XRD analysis of the initial β-Fe2O3 sample was recorded on a PANalytical X'Pert PRO diffractometer in the Bragg-Brentano geometry, equipped with an iron-filtered CoKα radiation source, an X'Celerator detector, a programmable divergence, and diffracted beam anti-scatter slits. Generally, 200 μL of a sample suspension was dropped onto a zero–background single–crystal Si slide, allowed to dry under vacuum at room temperature, and scanned in continuous mode (resolution of 0.017° in 2θ, scan speed of 0.008° in 2θ per second, 2θ range from 20° to 105°) under ambient conditions. The commercially available standards SRM640 (Si) and SRM660 (LaB6) supplied by the National Institute of Standards and Technology (NIST) were used to evaluate line positions and instrumental line broadening, respectively. The acquired pattern was processed using the X'Pert HighScore Plus software package (PANalytical, The Netherlands) and the PDF-4+ and ICSD databases. The room-temperature transmission 57Fe Mössbauer spectrum of the initial β-Fe2O3 sample was recorded with a Mössbauer spectrometer operating in constant acceleration mode and equipped with a 50 mCi 57Co(Rh) source of γ-rays. The collected Mössbauer spectrum was fitted using Lorentzian line shapes with the MossWinn software package based on the least-square method. The isomer shift values were referenced to a metallic α-Fe sample at room temperature.
