Abstract

For preparation of an effective sunscreens three nanoparticles were added to the matrix for suitable improving of sun absorption. In this study, different types of hollow TiO2, ZnO, Fe2O3 were synthesized by sol-gel method. To prepare TiO2 nanoparticles, tetra isopropoxide (TTIP) was used as a precursor and methanol as a solvent and its photocatalytic properties were investigated. Colorants and industrial wastewater were used to study photocatalytic properties of pure titanium dioxide, zinc oxide and iron oxide. The prepared products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared (FT-IR) spectroscopy and UV-vis absorption. All the synthesized products were used for preparation of sunscreen cream composite.
