Designing Characterization and Bioaccumulation of Nanomaterials for Degradation of Environmental Pollutants

Abstract

Environmental pollution, particularly from dyes and pigments, degrades water quality and poses health risks. Conventional water treatment systems often fail to address localized dye contamination, necessitating advanced decentralized solutions. This study explores the synthesis and characterization of six novel molybdenum and tin-based nanomaterials like MoO₃, MoS₂, and SnS₂ nanoparticles, along with their core-shell nanocomposites incorporating CoMnFe₂O₄ designed for efficient dye degradation under visible LED light. The nanomaterials were synthesized using the hydrothermal method and characterized through Raman Spectroscopy, FTIR, HRTEM, XRD, and UV-DRS. Structural analysis confirmed varied morphologies and crystallite sizes ranging from 4 to 32 nm. Optical band gap measurements indicated enhanced photocatalytic properties, attributed to oxygen vacancies and intercalation effects. These specific nanocomposites, highlight their potential as effective, eco-friendly photocatalysts for environmental pollutant removal.
