The progress of ferrites and ferrites-based nanocomposites has become extensively popular in the field of photocatalytic wastewater treatment. This class of compound exhibit several fascinating properties related with their high stability, low cost, ease of functionalization, and biocompatibility. Ferrites carry outstanding magnetic behavior that helps in their easy recovery from the aqueous system thus reducing the cost. The morphology and various properties such as magnetic, absorption, optoelectronic of magnetic ferrites can be varied and optimize by applying different synthetic routes and reaction conditions. With this background we have briefly presented and reviewed the latest development in the field of photodegradation of aqueous pollutants using ferrites based heterojunction. Especially, the type-II, Z-scheme and S-scheme based heterojunction for enhanced pollutant degradation under the exposure of light are thoroughly describe. Ferrites have inherent potential in water remediation applications hence many examples were consider to impart valuable knowledge to the readers. Nevertheless, the large-scale utilization of these magnetic nanoparticles still needs to be explored. Therefore, the gaps, challenges and future prospective of ferrites nanoparticles are also explained to unveil the un-scrutinized standard of ferrites nanoparticles.

“…Merging the sustainability with durability may be the key of transferring the photocatalytic process from the laboratory scale up to large applications. Until now there are many wide gap oxides (TiO 2 [ 4 , 5 ], SnO 2 [ 6 , 7 ], and ZnO [ 8 , 9 ]) and narrow band gap materials (Bi 2 WO 6 [ 10 , 11 ], Ag 3 PO 4 [ 12 , 13 ], BiPO 4 [ 14 , 15 ], g-C 3 N 4 [ 16 , 17 ], WO 3 [ 18 , 19 ], and BiOX [ 20 , 21 ]) studied for the potocatalytic removal of wastewater organic contaminants and indoor pollutants. The mono-components photocatalyst have disadvantages such as narrow visible light absorption [ 22 , 23 ], low specific surface area [ 24 , 25 ], and fast charge carriers recombination [ 26 , 27 ].…”

The photocatalyst materials correlation with the radiation scenario and pollutant molecules can have a significant influence on the overall photocatalytic efficiency. This work aims to outline the significance of optimizing the components mass ratio into a tandem structure in order to increase the photocatalytic activity toward pollutant removal. ZnO_SnO2 and TiO2_SnO2 tandem structures were obtained by the doctor blade technique using different mass ratios between the components. The samples contain metal oxides with crystalline structures and the morphology is influenced by the main component. The photocatalytic activity was tested using three radiation scenarios (UV, UV-Vis, and Vis) and two pollutant molecules (tartrazine and acetamiprid). The results indicate that the photocatalytic activity of the tandem structures is influenced by the radiation wavelength and pollutant molecule. The TiO2_SnO2 exhibit 90% photocatalytic efficiency under UV radiation in the presence of tartrazine, while ZnO_SnO2 exhibit 73% photocatalytic efficiency in the same experimental conditions. The kinetic evaluation indicate that ZnO_SnO2 (2:1) have a higher reaction rate comparing with TiO2_SnO2 (1:2) under UV radiation in the presence of acetamiprid.

Bismuth molybdate (γ-Bi 2 MoO 6 ) photocatalyst has drawn numerous attentions in the eld of photocatalysis because of its band gap (2.5eV ~ 2.8eV) and good visible light response (420 ≤ λ ≤ 500 nm). However, as a kind of bismuth molybdates, there are still few studies on Bi 3.64 Mo 0.36 O 6.55 (BMO), thus further exploration is needed. Herein, a simple re ux method was developed to synthesize the cubic phase BMO. This method is simple and easy to operate under atmospheric pressure, showing the great potential for large-scale production. In contrast with the nanosheet structure of Bi 2 MoO 6 , the morphology of BMO is mixture of nanorod and nanoparticle-like structure. The Motts curves show that conduction band position and the valence band position of BMO was 2.77 eV, -0.33eV and 2.44eV, respectively. A new mixed phase of 3Bi 2 O 3 •2MoO 3 was appeared in BMO crystal, showing that the phase transition of BMO began at 400℃. When BMO was calcined at 300℃, photocatalytic degradation rate is up to maximu.The photocatalytic activity of visible-light range was tested and compared with γ-Bi 2 MoO 6 . BMO had a better photodegradation activity than that of the Aurigillius phase γ-Bi 2 MoO 6 due to its larger band gap and the strong oxidation ability.
