Photocatalytic Degradation Properties of Li‐Cr Ions Substituted CoFe₂O₄ Nanoparticles for Wastewater Treatment Application

Abstract

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.

Onion Peel Waste Mediated-Green Synthesis of Zinc Oxide Nanoparticles and Their Phytotoxicity on Mung Bean and Wheat Plant Growth

“…Several other metallic nanoparticles have also been used for the same purposes like magnesium nanoparticles, Cr 2 O 3 nanoparticles by Ghotekar et al, and CoFe 2 O 4 NPs for wastewater treatment, etc. [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ].…”

Laser-ablative aqueous synthesis and characterization of elemental boron nanoparticles for biomedical applications

“…Such a bottleneck can be overcome by employing approaches of nanotechnology, which have already proved their efficiency in a variety of fields, including photovoltaics 9 , 10 , catalysis 11 – 13 , biomedicine 14 , 15 . Indeed, the use of boron-based nanoparticles (NPs) instead of molecular agents can offer much larger number of boron atoms and thus enhance the therapeutic outcome.…”

Spinel ZnCr2O4 nanorods synthesized by facile sol-gel auto combustion method with biomedical properties

“…Among many promising nanomaterials, spinel and spinel-like nanomaterials have been broadly considered in recent years due to their imperative properties in material science [ 12 – 15 ], resulting in versatile applications such as wastewater treatment [ 16 ], energy storage [ 17 ], photocatalytic [ 18 , 19 ], organic transformations [ 20 ] and nanomedicine [ 21 , 22 ]. Together with ternary spinel oxide materials, zinc chromite nanoparticles (ZnCr 2 O 4 NPs) have attracted interest owing to their special applications in the fields of photocatalysis [ 23 ], sensing [ 24 ], organic transformation [ 25 ], and superconductors [ 26 ].…”
