Abstract

The TiO2-SiO2 and ZnO-SiO2 composite films were prepared by sol-gel dip coating method. The surface morphology and crystal structure of thin films were characterized by means of scanning electron microscopy SEM with elementary dispersive X-ray analysis EDX and X-ray diffractometer XRD. Optical properties of films have been investigated using ultraviolet and visible spectroscopy UV-visible spectroscopy. The photocatalytic activity was established by testing the degradation and decolorization of methyl green MG from aqueous solution with artificial UV-light.
