A Thorough Analysis of the Chemical and Physical Characteristics of Metal Oxide Coated Fly Ash Cenospheres: Waste Generation in Thermal Power Plants and their Photocatalytic Research

Several nanocomposites prepared from a coating of metal/metal oxide nanoparticles on Cenospheres have a special property. The primary nanoparticles are closely stacked together without interparticle voids and formed on the cenosphere shell, providing a high surface area for the photocatalytic degradation of dyes. These numerous nanocomposites were characterised by various techniques such as Field emission electron scanning microscopy, energy dispersive X-ray, X-ray diffraction, Fourier Transformation Infrared, Ultraviolet-Visible spectroscopy, Scanning Electron Microscopy and Transmission Electron Microscopy. The mesoporous structure of all the nanoparticles and the strong adsorption ability of activated fly ash cenosphere accounted for the notable degradation performance.
