The Fe3O4–CuS@SiO2 photocatalyst, synthesized via a multistep assembly technique, effectively degraded methyl orange (MO) dye in an aqueous solution under visible light irradiation. solvothermal process generated Fe3O4–CuS nanoflowers, with Fe3O4 nanoparticles initially forming on the CuS surfaces. Subsequently, SiO2 shells were applied to using sol–gel resulting synthesis of photocatalyst. Within 20 min, prepared photocatalyst demonstrated remarkable MO degradation efficiency 94 ± 0.07% and sorption capacity 81.30 mg g−1. This efficacy was attributed synergistic effect between photocatalysis adsorption. superparamagnetic behavior catalyst at room temperature facilitated its high adsorbent recovery rate. proposed mechanism discussed considering various parameters capacity. Langmuir isotherm modeling (R2 = 0.9949) excellent fitting pseudo-second-order kinetics characterized adsorption data. Thermodynamic assessment revealed that is endothermic spontaneous (∆H° 110.0 kJ mol−1, ∆G° −3.03 −14.80 ∆S° 392.27 J mol−1 K−1). Notably, maintained 78% 0.20% after five sorption–desorption cycles for degradation, demonstrating exceptional reusability. These findings underscore superior environmental remediation potential

Clay minerals have been recognized as one of the cheap and effective materials for wastewater remediation. Among various clay minerals, montmorillonite (MMT) has received much attention due to its wide availability, low-cost promising properties such high porosity, mechanical strength, cation exchange capacity. Additionally, MMT swelling properties. These features make it an ideal material remediation applications. In addition, possessed good cationic capacity, making easier interact with molecules. composites exhibited selectivity catalytic activity contaminants elimination from wastewater. Surface modification functionalization identified a way improve MMT’s adsorptive performance endow light light-harnessing Thus, composites, especially metal metal-oxide nanoparticles, shown adsorption photocatalytic toward elimination/mineralization dyes, pharmaceuticals, heavy metals, other organic inorganic species. As such, can be adopted potential

Nanomaterials for Environmental Applications

Published: Jan. 1, 2023

The rapid growth in industrialization and population has resulted the generation permanence of a wide variety inorganic organic pollutants, posing potential risks to environment human health. degradation (either removal or reduction) sensing these pollutants from various environmental media (e.g., air, water, soil) are nowadays important problems worldwide. To address this issue, several nanotechnologies numerous nanostructured materials composites have been established for efficient remediation applications. This is ascribed their large surface area improved characteristics efficiency (like high reactive feature). current chapter reports such as filtration, photocatalysis, chemical reactions, absorption, adsorption, nanosensing, etc. It also offers an overview use environment. Novel materials, involving inorganic-based nanomaterials (NMs) zero-valent metal NMs, oxide-based silica-based NMs), carbon-based polymeric-based well nanocomposites were extensively reported discussed. These efficiently employed remediating halogenated herbicides, volatile compounds, chlorinated aromatic aliphatic hydrocarbons, pharmaceuticals, dyes, heavy metals, biological substances antibiotics, parasites, bacteria, viruses), gases (NOx, CO, SO2, etc.). Their efficiency, advantages, limitations compared Moreover, some directions future studies proposed.
