“…Catalyst regeneration and reusability is another important aspect to wastewater treatment so as to prevent further contamination as a result of the catalyst ( Argyle and Bartholomew, 2015 ; Taufik et al, 2016 ; Obaideen et al, 2022 ). Hence extensive research needs to be conducted on the sonophotocatalytic properties of retrievable materials including magnetic nanoparticles, films and fibers.…”

Due to water shortage and increased water pollution, various methods are being explored to improve water quality by treating contaminants. Sonophotocatalysis is a combination of two individual water treatment processes i.e., photocatalysis and sonocatalysis. With advantages including shorter reaction times and enhanced activity, this technique shows possible futuristic applications as an efficient water treatment technology. Herein, background insight on sonophotocalysis as a water and wastewater treatment technique as well as the general mechanism of activity is explained. The commonly used catalysts for sonophotocatalytic applications as well as their synthesis pathways are also briefly discussed. Additionally, the utilisation of sonophotocatalysis for the disinfection of various microbial species as well as treatment of wastewater pollutants including organic (dyes, pharmaceuticals and pesticides) and inorganic species (heavy metals) is deliberated. This review also gives a critical analysis of the efficiency, enhancement strategies as well as challenges and outlooks in this field. It is thus intended to give insight to researchers in the context of facilitating future developments in the field of water treatment, and advancing sonophotocatalysis towards large-scale implementation and commercialization.

“…ZnO coupled with CuO is used for various applications such as conductivity studies, photocatalytic activity, magnetic properties, and gas sensors. The presence of CuO along with ZnO can improve photocatalytic activity and increase spectral response, thus attracts significant interest, since the surface modification of semiconductor oxides with metals such as copper (Cu) or iron (Fe), an interfacial charge transfer mechanism, improves the photocatalytic activity against organic compounds (38)(39)(40)(41). Therefore, the incorporation of Fe2O3/Fe3O4 nanoparticles into CuO:ZnO nanocomposites to form ternary Fe2O3/Fe3O4:CuO: ZnO nanocomposites could provide promising catalysts.…”

The synthesis, characterization, and application of metal oxide nanocomposites have received increasing interest in the field of nanoscience and technology with several possible opportunities. Nanocomposites containing two or more dissimilar band gaps semiconductors provide exceptional properties to photocatalysts. A simple chemical co-precipitation method was employed to synthesize ZnO:CuO:Fe2O3 mixed metal oxide nanocomposites followed by calcination at 500 0 C. The prepared nanocomposites were characterized by XRD, FTIR, SEM, and TEM. The FTIR and XRD spectra confirmed the characteristic vibrations of ferrite atoms along with Cu-O and Zn-O vibrations. The crystallite particle size calculated by Debye Scherrer formula matched the size obtained by SEM and TEM images. The photocatalytic efficiency of the ZnO:CuO:Fe2O3 nanocomposites was assessed using crystal violet dye in the presence of sunlight. Variation in the concentration of Cu with respect to zinc in the nanocomposites enhanced photodegradation efficiency in this investigation. Our results indicated that the variation in the composition of ternary nanocomposite catalysts influence the competence for dye removal from waste water.
