“…The physicochemical properties of SFNPs depend mainly on the types, amounts, and positions of the M cations in the crystallographic structure. MFe 2 O 4 nanoparticles exhibit some advantages, such as stability, biocompatibility, low-cost, excellent magnetic properties, and easy separation [ 61 ]. Therefore, they have been widely used in the development of binary nanocomposites as photocatalysts for the photodegradation of pollutants.…”

Photocatalysts provide a sustainable method of treating organic pollutants in wastewater and converting greenhouse gases. Many studies have been published on this topic in recent years, which signifies the great interest and attention that this topic inspires in the community, as well as in scientists. Composite photocatalysts based on conducting polymers and metal oxides have emerged as novel and promising photoactive materials. It has been demonstrated that conducting polymers can substantially improve the photocatalytic efficiency of metal oxides owing to their superior photocatalytic activities, high conductivities, and unique electrochemical and optical properties. Consequently, conducting polymer/metal oxide composites exhibit a high photoresponse and possess a higher surface area allowing for visible light absorption, low recombination of charge carriers, and high photocatalytic performance. Herein, we provide an overview of recent advances in the development of conducting polymer/metal oxide composite photocatalysts for organic pollutant degradation and CO2 conversion through photocatalytic processes.

“…Magnesium ferrite nanoparticles, one of the spinel ferrites, have a magnetic property, which makes them to be separated easily from water as well (Liu et al 2021). This simple and cost-effective separation can make magnesium ferrite to be used in several cycles through regeneration (Reddy and Yun 2016;Suresh et al 2021). Magnetic behavior of magnesium ferrite nanoparticles can be analyzed by vibrating sample magnetometer (VSM).…”

“…According to World Health Organization (WHO) report 2019, about 2 × 10 9 people are using contaminated water for drinking which causes diarrheal death of 4.85 × 10 5 people per year. They also predicted that almost 50% of world's population will be under water stressed zone in 2025 (WHO 2019;Suresh et al 2021). Therefore, continuous supply of safe and healthy water is a prime concern for all governments, which requires large investment for the infrastructures of water supply.…”

Nanoadsorbents having large specific surface area, high pore volume with tunable pore size, affordability and easy magnetic separation gained much popularity in recent time. Iron-based nanoadsorbents showed higher adsorption capacity for different pollutant removal from water among other periodic elements. Spinel ferrite nanomaterials among iron-bearing adsorbent class performed better than single iron oxide and hydroxides due to their large surface area, mesoporous pore, high pore volume and stability. This work aimed at focusing on water treatment using magnesium ferrite (MgFe 2 O 4 ) nanomaterials. Synthesis routes, properties and pollutant adsorption were critically investigated to explore the performance of magnesium ferrite in water treatment. Structural and surface properties were greatly affected by the factors involved in different synthesis routes and iron and magnesium ratio. Complete removal of pollutants through adsorption was achieved using magnesium ferrite. Pollutant adsorption capacity of MgFe 2 O 4 and its modified forms was found several folds higher than Fe 2 O 3 and Fe 3 O 4 nanomaterials. In addition, MgFe 2 O 4 showed strong stability in water than other pure iron oxide and hydroxide. Modification with graphene oxide, activated carbon, biochar and silica was demonstrated to be beneficial for enhanced adsorption capacity. Complex formation was suggested as a dominant mechanism for pollutant adsorption. These nanomaterials could be a viable and competitive adsorbent for diverse pollutant removal from water.

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.
