Figure 1

Rietveld refinement of the XRD patterns for (a) S–Fe and (b) S–Ti samples at room temperature. The top and bottom Bragg positions correspond to F d − 3 m and P b c m respectively in both panels. Crystal structures of S–Ti sample considering ionic radii of the atoms for representation in (c) Cubic and (d) Orthorhombic phases. Green and brown color correspond to two different sites of Fe having + 2 and + 3 oxidation states respectively in both structures. Electron density distribution difference for (e) S–Fe and (f) S–Ti along ab plane considering cubic spinel phase only. The atomic nomenclature is removed for better visibility in (f).
