“…[18]. There are several diverse approaches for fabrication of magnetite nanoparticles like co-precipitation method [19], sol-gel method [20], electron beam lithography [21], gas segment deposition [22] ,oxidation method [23], reduction method [24], hydrothermal method [25], solvothermal method [26], thermal decomposition method [27], flow injection method [28], electrochemical method [29], vapor phase method [30], supercritical method [31], sonochemical decomposition method [32], nonreactors method [33] microbial method [34], electrochemical synthesis [35], micro emulsion techniques [36], hydrolysis [37], and microwave assisted synthesis [38]. The coprecipitation approach in aqueous media is a favorable method for magnetite synthesis since the synthesis process is easy and the environmental impact is minimal.…”

Magnetite (Fe 3 O 4 ) nanoparticles were controllably prepared by a co such as sodium hydroxide and ammonium hydroxid characterized by using X-ray diffraction (XRD), Fourier transform infrared (FT transmission electron microscope (TEM) and vibrating ammonium hydroxide produced magnetite nanoparticles with smaller particle size (14 nm), compared to those prepared (22 nm) using sodium hydroxide precipitating agent. In addition, we found that the saturat magnetite nanoparticles was influenced by the obtained particle size. The determined saturation magnetization of the generated magnetite nanoparticles was found to be ca.61.3, 65.1 emu/g for those prepared using NaOH and N precipitating agents, respectively.

“…The initial range of COD values employed were 100-700 ppm and the removal of COD in terms of percentage was 77-95% (Al-Ananzeh 2021). All copper nanostructures produced exhibited good photocatalytic activity in the range of 95Á0-98Á0% for the breakdown of safranin dye in the presence of UV radiation for 70 min (El-Berry et al 2021).…”

Water scarcity is not a novel issue. It has already affected almost every continent in this blue planet. It is driven by two primary sources: increasing demand for fresh water due to the increase in population and overexhaustion of the available freshwater resources. During the past decade, stress has been given to extract fresh, clean and safe potable elixir of life from the bountiful stores of sea water by exploiting various technologies. As nanomaterials are providing promising solutions to almost all our problems, they are again being accessed in order to combat the problem of global freshwater scarcity. Desalination methods have marvellously improved under the impact of nanomaterials. Different metallic nanomaterials are being used to serve this purpose; for example, silver, iron, zinc, titanium dioxide in addition to natural and synthetically derived polymeric bionanomaterials. In the present paper, a brief account of all the metallic nanomaterials which are being used for treatment of water has been provided by thorough investigation on the research done till now. It strives to throw light on various materials and methods which are based on the exploitation of nanotechnology for the treatment of water.

“…Radical scavenger experiments were carried out using the nanocomposites to evaluate the types of reactive species that formed during the photocatalytic degradation process. In this experiment, 2 M of ethylenediaminetetraacetic acid disodium salt (Na 2 EDTA) and isopropanol (IPA) were used as superoxide radicals and hydroxyl radical scavengers, respectively [39,40]. Figure 8 shows the results of the radical scavenger degradation of three different dyes.…”

Environmental pollution is a major threat that increases day by day due to various activities. A wide variety of organic pollutants enter the environment due to petrochemical activities. Organic contamination can be unsafe, oncogenic, and lethal. Due to environmental issues worldwide, scientists and research communities are focusing their research efforts on this area. For the removal of toxic organic pollutants from the environment, photocatalysis-assisted degradation processes have gained more attention than other advanced oxidation processes (AOPs). In this manuscript, we report a novel photocatalysis of copper and lanthanum incorporating cerium oxide (CeO2) loaded on graphene oxide (Cu/La/CeO2/GO) nanocomposites successfully synthesized by hydrothermal techniques. XRD results showed the presence of dopant ions and a crystalline structure. FESEM images showed that the surface morphology of the synthesized nanocomposites formed a rod-like structure. The highlight of this study is the in-situ synthesis of the novel Cu/La/CeO2/GO nanocomposites, which manifest higher photodegradation of harmful organic dyes (Rhodamine B (RhB), Sunset Yellow (SY), and Cibacron Red (CR)). In Cu/La/CeO2/GO nanocomposites, the dopant materials restrict the rapid recombination of photoinduced electron–hole pairs and enhance the photocatalytic activity. The degradation percentages of RhB, SY, and CR dye solution are 80%, 60%, and 95%, respectively. In summary, the synthesized nanocomposites degrade toxic organic dyes with the help of visible light and are suitable for future industrial applications.
