Abstract

In this work, we report on the synthesis of flower-like tungsten oxide nanoparticles (WO₃ NPs) using a simple precipitation method. This paper reports a simple method for synthesizing flower-like WO₃ NPs, which can be used for environmentally treating hazardous organic pollutants. The photocatalytic degradation of model artificial Orange II and Congo red was assessed under natural sunlight irradiation. The surface morphologies, crystallinity, and binding energy of the synthesized WO₃ NPs were determined. The synthesized WO₃ NPs exhibited good photodegradation percentages of approximately Orange II (97.6%) and Congo red dye (98.2%) after 120 min of irradiation. Furthermore, the WO₃ NPs maintained their degradation ability for up to three cycles. In addition, WO₃ NPs were examined in different metal ions sensing (Hg²⁺, Fe²⁺, Cu²⁺, Ni²⁺, and Cd²⁺) in an aqueous solution. The results showed that the WO₃ NPs exhibited excellent Cd²⁺ ion sensing. Based on the investigations, WO₃ NPs proved to be an efficient photocatalyst and hold promise as the best material for future applications in preventing water pollution.
