Abstract

This paper describes the analysis and characterization of Na y WO x bronze nanowires bundles and evaluation of their effective adsorption of methylene blue dye (MB). The Na-doped WO x bronze nanowires bundles were first synthesized via a simple solvothermal method, which were then fully characterized by using different techniques including TEM, XRD, XPS and UV-Vis, to validate the successful Na + insertion into the WO x framework. The adsorption activities of the resulting Na y WO x bronze nanowires bundles, compared with the undoped WO x form, were investigated by evaluating the adsorption effect on methylene blue under both UV and visible light irradiations. An enhanced adsorption performance of the Na-doped WO x bronze samples was recorded, which demonstrated a 90% of removal efficiency of the MB under different conditions (dark, visible and UV light). Moreover, the Na y WO x bronze samples also offered a 4 times better kinetic rate of MB removal than the plain WO x nanowires.
