Synthesis of nano particles for photo electro chemical degradation of dye effluent

The increasing discharge of dye-containing effluents from textile, paper, leather, and dyeing industries poses a serious threat to aquatic ecosystems and human health due to their high toxicity, chemical stability, and resistance to conventional treatment methods. Photoelectrochemical (PEC) degradation has emerged as an effective and environmentally friendly advanced oxidation process for the removal of such persistent organic pollutants. The present study focuses on the synthesis of nanomaterials and their application in the photoelectrochemical degradation of dye effluents. In this work, nanostructured materials are synthesized using suitable chemical methods to obtain controlled particle size, high surface area, and enhanced photoactivity. The synthesized nanomaterials are thoroughly characterized using analytical techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV–Visible spectroscopy, and electrochemical measurements to evaluate their structural, morphological, optical, and electrochemical properties. The photoelectrochemical performance of the prepared nanomaterials is investigated using a model dye effluent under visible or UV light irradiation.The degradation efficiency is assessed by monitoring the decrease in dye concentration through UV–Visible spectroscopic analysis, while the effects of operational parameters such as pH, applied potential, irradiation time, and initial dye concentration are systematically studied. The enhanced degradation efficiency is attributed to the improved charge separation, reduced recombination of photogenerated electron–hole pairs, and increased generation of reactive oxygen species facilitated by the nanomaterial-based photoelectrodes. The results of this study demonstrate that the synthesized nanomaterials exhibit significant potential as efficient photoelectrodes for the treatment of dye-contaminated wastewater, offering a promising and sustainable approach for industrial effluent remediatiON
