Abstract
The authors report a facile route for the large scale synthesis of CuO/ZnO/Si ternary system achieved by non-equilibrium synthesis using High Energy Ball Milling (HEBM) technique. The synthesized material was found highly efficient for the photo-degradation of a hazardous dye Indigo Carmine, a widely used dye in textile industries with major threats to our environment. The structural properties of the prepared material were evaluated using X-ray diffraction and field emission scanning electron microscopy, which revealed, that the optimization of milling duration plays a crucial role for the formation of such ternary system. UV–Vis-NIR spectroscopy yielded broadband absorption of light over the region 1100–350 nm. The photocatalytic activities of CuO/ZnO/Si ternary system were systematically explored by monitoring the fall in specific absorption peak intensity of the aqueous Indigo Carmine solution exposed under artificial light source.
