Equimolar TiO2-ZrO2 nanocomposite prepared by sol-gel method showed higher photocatalytic activity and superior adsorption for dye solution. Interfacial contacts and lattice substitution contributed to its enhanced performance.
Equimolar TiO2-ZrO2 nanocomposite was prepared by sol-gel method with predominant tetragonal phase for zirconia and investigated for photodegradation of Alizarin Yellow GG dye under natural sunlight. Interfacial contacts enabling Zr-O-Ti bonding with preferred orientation of (101)TiO2//(101) ZrO2 were seen at heterojunctions, and partial Zr4+ substitution in TiO2 lattice enhanced the acidity of TiO2. Increase in surface area, pore size and pore volume in nanocomposite contributed to its superior adsorption for dye solution. TiO2-ZrO2 showed much higher photocatalytic activity of 68% than by parent TiO2. EIS spectra of TiO2-ZrO2 showed low impedance than titania supporting the higher activity of the nanocomposite photocatalyst. (C) 2021 Elsevier Ltd. All rights reserved.
