Abstract

This paper describes the analysis and characterization of Na_yWO_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_yWO_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_yWO_x bronze samples also offered a 4 times better kinetic rate of MB removal than the plain WO_x nanowires. View Full-Text
