Using cotton fibers as templates, quasi‐one‐dimensional bismuth tungsten oxide (Bi 2 WO 6 ) nanostructures were successfully synthesized using a combination of solution dipping and calcinating at 500°C. The Bi 2 WO 6 nanostructures were characterized using X‐ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, and N 2 adsorption and desorption measurements. Their optical property was studied using a UV‐vis spectrum, and the photocatalytic activity was investigated by degrading the organic compound. It was found that the Bi 2 WO 6 nanostructures maintained the quasi‐one‐dimensional morphology of the cotton fibers and were composed of nanoparticles about 40 nm in size. The mechanism of formation of the quasi‐one‐dimensional Bi 2 WO 6 nanostructures was also discussed. Moreover, the quasi‐one‐dimensional Bi 2 WO 6 nanostructures exhibited good visible light absorption and could efficiently decompose rhodamine B under visible light irradiation.
