X-ray powder diffraction patterns of as-synthesized nanomaterials containing (a) yttrium, (b) zirconium, (c) niobium, (d) ruthenium, and (e) rhodium. Indexing of the diffraction peaks are performed for the corresponding phases as displayed by the reference patterns underneath the XRPD patterns, where index patterns correspond to (b) ZrO₂ (ICDD card: 00-001-0750), (c) Nb₂O₅ (ICDD card: 00-028-0317), (d) Ru (ICDD card: 01-089-4903), and (e) Rh (ICDD card: 03-065-2866).
