Abstract
This article reports a portable, flexible gallium doped zinc oxide/polystyrene/cellulose (GZO/PSC) nanocomposite and the development of a hybrid material for various applications primarily in water treatment and renewable energy. With respect to a green technology, our nanocomposite can be easily eliminated from the pollution mixture, after using. A complete morphological, structural, mechanical, chemical, and optical characterization was made using different analysis techniques. Secondly, catalytic activities for photocatalytic and sonocatalytic degradation were evaluated by decolorizing methylene blue/orange in an aqueous solution under dark, light, and ultrasonic exposure. The synthesized GZO NPs and GZO/PSC hybrid nanocomposite showed a high decolorization efficiency in a short time. These samples destroyed the MB dye molecule (98 and 96 ± 1%) in just 10 and 45 min respectively, under UVA irradiation. Just 7 min simultaneous irradiation of both UVA light/ultrasonic resulted in 95% destruction of MB molecules for GZO NPs (neat fillers). Our results show that the GZO/PS and GZO/PSC hybrid films (Ga:ZnO@PCS) can be easily used in both the field of flexible luminescent devices and water treatment, respectively. At the same time, no photocatalyst remained in the reaction system after wastewater treatment. This simple approach can be upscaled for industrial use.
