Mesoporous TiO₂ coated ZnFe₂O₄ nanocomposite loading on activated fly ash cenosphere for visible light photocatalysis.

ABSTRACT: Several activated fly ash cenosphere (AFAC) supporting TiO₂ coated ZnFe₂O₄ (TiO₂/ZnFe₂O₄/AFAC) photocatalysts were prepared by sol-gel and hydrothermal methods. These photocatalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), UV-vis diffuse reflectance spectroscopy (UV-DRS) and nitrogen adsorption analyses for Brunauer-Emmett-Teller (BET) specific surface area measurements. We found that the main components of spherical AFAC were mullite (Al₆Si₂O₁₃) and SiO₂; the crystallite size of the TiO₂/ZnFe₂O₄ nanocomposite was less t
