“…Some recent studies on the photodegradation of MV are listed in Table 4. From the results listed in this table, we can conclude that the CeO 2 @CuFe 2 O 4 photocatalyst shows has excellent catalytic performance compared with other photocatalysts previously reported by other authors, especially in the range of visible light 57–60 …”

A direct Z-scheme photocatalyst CuFe 2 O 4 @CeO 2 core-shell was applied in the photocatalytic degradation of the methyl violet dye 2B (MV). In first, CuFe 2 O 4 and CeO 2 were synthesized via sol-gel method, and then CuFe 2 O 4 @CeO 2 nanocomposite was prepared using microwave process. The nanoparticles were characterized by thermogravimetric analysis (TG and derivative thermogravimetry [DTG]), atomic absorption spectroscopy (AAS), Brunauer-Emmett-Teller (BET) analysis, Xray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), energy dispersive-X-ray (EDX) and ultraviolet (UV)visible diffuse reflectance/absorption spectroscopy. The photocatalytic activity of CuFe 2 O 4 @CeO 2 nanocomposite was evaluated by the photo-degradation of the MV under UV and visible-light irradiation. MV does not rapidly degrade itself in UV or visible-light but the process is accelerated upon the addition of semiconductors with a wide band-gap. The CuFe 2 O 4 @CeO 2 nanocomposite shows an important MV decomposition rate under visible-light irradiation (95.35% within 1.5 h) as compared to UV-light (86.10% within 2.5 h). The excellent activity of CuFe 2 O 4 @CeO 2 under UV and visible-light was mainly attributed to direct Z-scheme which are originated from a core-shell structure which prompted the generation of ˙OH radical species responsible for the photo-degradation of the substance. However, this could also be due to the large specific surface area and/or efficient UV-vis harvesting.

“…OH radicals photodegrades CV dye molecules for H 2 O, CO 2 , and other mineral acids as degradation products as given in Equation (). [ 76,77 ]

CV dye + \dot{O H} + \dot{normalO} 2^{-} \to {CO}_{2} {+ H}_{2} O

As it is well known that catalysis is a surface phenomenon, and B site ions are reported to be exposed on the surface of the ferrite NPs. [ 2 ] Therefore, the catalytic activity of ferrite NPs is due to the presence of Cr 3+ and Li 1+ ions on the B site, and reduced particle size for dopant concentration of 0.03 leads to a larger surface area and higher catalytic activity.…”

Increasing living standards, urbanization, industry, and inadequate wastewater management are all contributing factors in the release of toxic wastewater into the aquatic environment.The industrial sectors producing dyes and pigments are seen as major environmental hazards due to the vast amounts of water they require throughout the manufacturing process. [1][2][3] Toxic organic pollutants, such as fertilizers, chlorinated solvents, and volatile organic compounds (VOCs), as well as nitroaromatic compounds, phenols, and dye-based chemicals, are already poisoning natural water sources. [4,5] Organic dyes, for example, are widely used in the textile industry, jute and threads industries, pharmaceutical industries, petrochemical industries, and other sectors and are discharged as effluent into water resources such as ponds, lakes, rivers, and other bodies of water. These organic dyes and their products are typically poisonous, and they have the potential to induce significant mutagenesis and carcinogenic consequences when they come into contact with living organisms. [6,7] Treatment of water contaminated with different chemical and biological pollutants has been accomplished via a variety of methods such as biological treatment, activated carbon adsorption, ultrafiltration, reverse osmosis, and electrochemical oxidation.

“…Also, it was found that the highest degradation efficiency of 85% was exhibited by Gd: 2 BFO against crystal violet in comparison to pure BFO. 152 The photocatalytic activity of yttrium (Y)-doped and undoped BiFeO 3 was investigated for the degradation of methylene blue under direct sunlight. The data from experiments showed that BiFeO 3 photocatalysts were recyclable up to four consecutive cycles without any remarkable loss of their photocatalytic efficiencies as shown in Fig.…”
