Preparation and UV Shielding Properties of Zn/Ce/Ti Oxide and Composite Oxide by Combustion Method

Abstract

ZnO, CeO₂, TiO₂, ZnO-CeO₂, CeO₂-TiO₂, ZnO-TiO₂, and ZnO-CeO₂-TiO₂ powders have been fabricated using a combustion synthesis method for an application as UV Shielding agent for light stability of paraffin wax. Ascorbic acid (C₆H₈O₆) was used as a new fuel and nitrate as raw materials. These powders are obtained when their processing parameters are optimized. The fuel (i.e., ascorbic acid) was used for producing the ZnO, CeO₂, TiO₂, ZnO-CeO₂, CeO₂-TiO₂, ZnO-TiO₂, and ZnO-CeO₂-TiO₂ powders. The produced particles have been characterized using SEM for the particle morphology, UV, and IR for absorbance properties, XRD for phase identification, and analysis of the particle size distribution and identification. In addition, these particles have shown good UV shielding properties, which provide an opportunity for these materials are used to improve light stability of paraffin wax.
