Precursor method for the synthesis of highly dispersed ZrO2 doped with scandium

The solid solutions of Zr_1–xSc_xO_2–δ (0 < x ≤ 0.1) were prepared using a precursor technology, and their structural, optical, and photocatalytic characteristics were studied. Mixed formates synthesized by an original method were used as precursors. Scandium favored the formation of ZrO₂ in tetragonal syngony and increased its photoactivity in the UV range.
