In this work, flower-like tungsten oxide nanoparticles (WO3 NPs) were synthesized using a simple precipitation method. The synthesized WO3 NPs showed good photodegradation percentages for Orange II and Congo red dyes under natural sunlight irradiation. Additionally, the WO3 NPs exhibited excellent sensing ability for Cd2+ ions in aqueous solutions. Based on the investigations, WO3 NPs proved to be an efficient photocatalyst and hold promise for future applications in preventing water pollution.
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.
