A simple hydrothermal route for the preparation of novel Na–Y–W nano-oxides and their application in dye degradation

Abstract

The fabricated NaY(WO4)2 was identified through diverse analysis methods. Therefore, to optimize NaY(WO4)2 morphology, saccharide carbohydrates were manipulated as a capping agent. In this study, glucose, fructose, lactose, cellulose, and starch were utilized as the capping agents. SEM images show that fructose was the optimal capping agent for achieving uniform and well-shaped nanoparticles. The photodegradation of organic dyes such as M.O and Rd.B by NaY(WO4)2 was evaluated under UV and Vis light. The bandgap energy of the as-prepared sample was measured by the Tauc plot, and was found to be nearly 3.85 eV. To study the photocatalytic characteristics, the influence of dye dosage and reusability on photodegradation behavior were investigated.
