“…Conventional materials, like ZnO, TiO 2 , ZrO 2 , CeO 2 , and SnO 2 are only active in ultraviolet (UV) light, which accounts for just 4% of the solar spectrum, limiting their usage in simulated or direct solar-light dye degradation over a broad visible range (Banerjee et al 2014 ; Nkosi et al 2014 ; Ovodok et al 2018 ; Natarajan et al 2018 ; Yadav et al 2019 ; Kannan et al 2020 ; Aliabadi et al 2020 ; Luque et al 2021 ). The advantage of using iron-based photocatalysts is that they can absorb 39% or more of the solar-light composition in visible light and hence have effective degradation efficiencies (Hassani et al 2018 ; Madihi-Bidgoli et al 2021 ). Hetero-mixed interfaces with more than two metal oxides have shown to be the most successful method for producing visible light photoactive materials.…”

A novel visible-light-sensitive ZnVFeO4 photocatalyst has been fabricated by the precipitation method at different pH values for the enhanced photocatalytic degradation of malachite green (MG) dye as a representative pollutant under visible light irradiation at neutral pH conditions. The structure and optical characteristics of the prepared photocatalysts were investigated by XRD, FTIR, N2 adsorption–desorption, TEM, diffuse reflectance spectroscopy (DRS), and photoluminescence (PL) analyses. In addition, the photocatalytic activity of ZnVFeO4 photocatalysts superior the efficiency to be more than that of the mono and bi-metal oxides of iron and iron zinc oxides, respectively. The best sample, ZnVFeO4 at pH 3, significantly enhances the degradation rate under visible light to be 12.7 × 10−3 min−1 and can retain a stable photodegradation efficiency of 90.1% after five cycles. The effect of the catalyst dose and the initial dye concentration on the photodegradation process were studied. This promising behavior under visible light may be attributed to the low bandgap and the decreased electron–hole recombination rate of the ZnVFeO4 heterostructures. The scavenger experiment confirmed that the hydroxyl radicals induced the MG photodegradation process effectively. Hence, the ZnVFeO4 is a reliable visible-light-responsive heterostructure photocatalyst with excellent potential for the photodegradation of organic pollutants in wastewater treatment.

This paper describes the crystal interphase impact of ZnFe 2 O 4 –Ag in the photodegradation of Rhodamine B. Prepared ZnFe 2 O 4 nanoparticles (NPs) were deposited with Ag NPs to offer ZnFe 2 O 4 –Ag (0–2.5%). An X-ray diffraction peak corresponding to the Ag NPs was detected if the particle content reached about 2.0%, observing multiple crystalline interphases in HR-TEM. Magnetic saturation (Ms) was increased ∼160% times for ZnFe 2 O 4 –Ag (7.25 to 18.71 emu/g) and ZnFe 2 O 4 (9.62 to 25.09 emu/g) if the temperature is lowered from 298 to 5.0 K; while for Fe 3 O 4 (91.09 to 96.19 emu/g), the Ms increment was just about 5.6%. After analyzing the DFT–Density of State, a decrease of bandgap energy for ZnFe 2 O 4 –Ag 6 from the influence of the size of Ag cluster was seen. Quantum yield (Φ) was 0.60 for ZnFe 2 O 4 , 0.25 for ZnFe 2 O 4 –Ag (1.0%), 0.70 for ZnFe 2 O 4 –Ag (1.5%), 0.66 for ZnFe 2 O 4 –Ag (2.0%), and 0.66 for ZnFe 2 O 4 –Ag (2.5%), showing that the disposition of Ag NPs (1.5–2.5%) increases the Φ to >0.60. The samples were used to photo-oxidize RhB under visible light assisted by photopowered Langmuir adsorption. The degradation follows first-order kinetics ( k = 5.5 × 10 –3 min –1 ), resulting in a greater k = 2.0 × 10 –3 min –1 for ZnFe 2 O 4 –Ag than for ZnFe 2 O 4 (or Fe 3 O 4 , k = 1.1 × 10 –3 min –1 ). DFT-total energy was used to analyze the intermediates formed from the RhB oxidation. Finally, the ZnFe 2 O 4 –Ag exhibits good antibacterial behavior because of the presence of Zn and the Ag components.
