Semiconductor photocatalysis has become an increasingly promising technology in environmental wastewater treatment.The present work reports a simple technique for the orange zinger tomato preparation of platinum-deposited TiO2 catalysts and its immobilization on ordinary ceramic tiles.The Pt/TiO2 is characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDAX), and diffuse reflectance spectroscopy (DRS).Deposition of Pt on TiO2 extends the optical absorption of the latter to the visible region which makes it attractive for solar energy application.Optimum loading of ultrastar dc hc550 Pt on TiO2 was found to be 0.

5%.The Pt/TiO2 is coated on ceramic tiles and immobilized.This catalyst was found effective for the solar photocatalytic removal of chemical and bacterial pollutants from water.Once the parameters are optimized, the Pt/TiO2/tile can find application in swimming pools, hospitals, water theme parks, and even industries for the decontamination of water.
