Resumo

High-entropy single-phase oxides with the perovskite structure Ca(Ti0.25Sn0.25Nb0.125Ta0.125M0.25)O3 (M = Fe, Zr) were synthesized for the first time by a simple one-step ceramic method and characterized by X-ray diffraction analysis. The powders were subjected to mechanical activation, which resulted in a partial phase transition from an orthorhombic phase to a tetragonal one. Both compositions demonstrated the ability to reduce Cr(VI) when illuminated with uV light and high sorption activity with respect to the methylene blue dye.
