Nanomaterials Based on Collaboration with Multiple Partners: Zn₃Nb₂O₈ Doped with Eu³⁺ and/or Amino Substituted Porphyrin Incorporated in Silica Matrices for the Discoloration of Methyl Red.

ABSTRACT: Designing appropriate materials destined for the removal of dyes from waste waters represents a great challenge for achieving a sustainable society. Three partnerships were set up to obtain novel adsorbents with tailored optoelectronic properties using silica matrices, Zn₃Nb₂O₈ oxide doped with Eu³⁺, and a symmetrical amino-substituted porphyrin. The pseudo-binary oxide with the formula Zn₃Nb₂O₈ was obtained by the solid-state method. The doping of Zn₃Nb₂O₈ with Eu³⁺ ions was intended in order to amplify the optical properties of the mixed oxide that are highly influenced by the coordination environment of Eu³⁺ ions, as confirmed by density functional theory (
