Abstract

Nanocomposites have emerged as effective materials for environmental cleanup owing to their distinctive physicochemical features, elevated surface area, and increased reactivity. This review paper presents a comprehensive overview of nanocomposites used for environmental remediation, focusing on their synthesis, mechanisms, recent advancements, challenges, and future directions. The paper classifies nanocomposites into five primary types which are discussed in detail in this review. Each type offers distinct advantages in pollutant degradation and heavy metal removal through adsorption, photocatalysis, Fenton and Photo-Fenton reactions and membrane filtration. Notably, adsorption and photocatalytic mechanisms, including charge separation and ROS generation, are highlighted for their effectiveness in tackling contamination. Recent advancements in synthesis techniques emphasize green synthesis approaches, heterojunction formation, and surface functionalization to enhance performance. Despite the progress, challenges such as nanoparticle agglomeration, recyclability, toxicity, and environmental impacts persist. Addressing these limitations through innovative strategies is crucial for sustainable application. Future research should focus on developing multifunctional nanocomposites for integrated remediation, leveraging artificial intelligence for material optimization, and designing eco-friendly and biodegradable materials. By overcoming current challenges, nanocomposites hold significant potential to revolutionize environmental remediation strategies.
