Supplemental Material. A description of the experimental methods, supplementary figures and tables. Figure S1. The PXRD pattern of Mn2O3@SiO2 core-shell nanostructures. Reflections corresponding to Mn2O3 (cubic) with a broad feature in the 2 theta range from 20° to 30° are observed indicating the presence of amorphous silica coated on Mn2O3 particles. Figure S2. EDAX spectrum of Mn2O3@SiO2 core-shell nanostructures. Figure shows peaks corresponding to Mn, O, and Si confirming their presence in the core-shell nanostructures. Table S1 Details of the IR frequencies for functionalized core-shell nanostructures
