In this study the photodegradation of aqueous solution of recalcitrant organic pollutant Orange I was investigated by using chromium substituted zinc ferrite, ZnFe 2−x Cr x O 4 (x=0, 0.25, 0.5, 1.0, 1.50, 2.0) catalysts, for the first time, under both UV and visible light irradiation. The photocatalytic process was promoted when Fe 3+ cations were substituted with Cr...
Aluminum substituted zinc ferrite catalysts were prepared by the sol–gel auto-combustion method and characterized by using Mössbauer spectroscopy and nitrogen adsorption–desorption isotherm measurements. The photocatalytic activity of ZnFe 2−x Al x O 4 (0≤x≤2) spinel ferrites was evaluated for the first time on Orange I azo dye degradation under UV light illumination. The results...
