Preparation of cerium zinc oxide nanocomposite derived by hydrothermal route coated on glass and its application in water treatment

Abstract

Ce and Zn oxide nanomaterials were effectively fabricated via one pot green and eco-friendly hydrothermal route. Ce and Zn oxide nanomaterials, terpineol, ethyl cellulose, and double distilled water were grinded and sonicated in four steps for improved coating. An efficient sonication route for improved coating of nanocomposite paste on glass for environmental application was investigated. Better dispersion of nanopaste by sonication for coating on glass was effective. The paste was deposited on the glass substrate through the Doctor Blade-coating and annealed in atmosphere at 550°C. The Ce and Zn oxide nanomaterials were characterized by thermo gravimetric analysis (TG-DTG), Fourier transform infrared, X-ray diffraction, field emission scanning electron microscopy, energy dispersive X-ray spectrometry, and UV–vis diffuse reflectance (DRS) spectroscopy techniques. Experimental studies for photocatalytic degradation of di-azo Naphthol Blue Black (NBB) textile dye from water systems revealed that Ce–Zn coupled oxide nanocomposite coated on glass was more effective in degradation of the dye compared with single Ce and Zn oxide nanomaterials.
