Abstract
The escalating concerns regarding environmental pollution have spurred significant interest in developing efficient photocatalytic materials for the degradation of organic contaminants. This study investigates nanocomposites for visible-light photocatalytic destruction of organic pollutants, considering the limitations of UV-only photocatalysts. Given that a significant fraction of the solar spectrum is visible light, the capacity to utilize this light for catalytic reactions is critically important. The nanocomposite consists of a semiconductor material doped with noble metal nanoparticles, designed to enhance light absorption and charge separation efficiency. Through a series of synthesis techniques and characterization methods including X-ray diffraction, scanning electron microscopy, and UV-Vis spectroscopy, the structural and optical properties of the nanocomposite are thoroughly investigated.
