Surface Modification of Zinc Ferrite with Titanium to Be a Photo-Active Catalyst in Commercial LED Light

Abstract

Titanium-doped zinc ferrite was used as a photo catalyst for breaking down C-C and C-H bonds of methylene blue dye as a model for the decomposition of organic pollutants. Different concentrations of Ti were used to impede into the spinel structure of zinc ferrite by in situ addition during the preparation. Different characterization techniques were used to characterize the prepared materials including the deep analysis of the electronic spectra, which proved the surface modification of ferrite due to the Ti doping. In addition, we make a comparison study of photo degradation using ordinary UV irradiation and commercial LED light irradiation, which gives very promising results. A correlation between the structure and the photo catalytic behavior of the materials is assigned.

“…However, in ZnFe 2 O 4 -Cu, the presence of Cu NPs reduces overall magnetism to a certain extent. This reduction allows for a decreased agglomeration [ 92 ].…”

“…However, in ZnFe2O4−Cu, the presence of Cu NPs reduces overall magnetism to a certain extent. This reduction allows for a decreased agglomeration [92]. To conduct a more in-depth investigation of the EDX output, elemental mapping analysis was carried out for Fe2O3, ZnO, ZnFe2O4, and ZnFe2O4−Cu nanomaterials, as shown in Figure S1a-d.…”
