“…From the N 2 isotherms, the BET specific surface area is calculated to be 21.1140 m 2 /g. As per some previous reports, the Bi 2 WO 6 samples synthesized by the conventional hydrothermal methods display surface areas of 13.36 m 2 /g, 10.228 m 2 /g, and 15.9 m 2 /g . Thus, the specific surface area of the Bi 2 WO 6 nanopowder synthesized by the MH method in this study is larger than that of the samples synthesized by the conventional hydrothermal methods.…”

The adsorption characteristics of the methylene blue (MB) dye on Bi2WO6 nanopowder, which was synthesized by the microwave‐assisted hydrothermal method, were studied. The structural and morphological properties of the Bi2WO6 sample were examined by scanning electron microscopy, transmission electron microscopy, and powder X‐ray diffraction. The change in the dye concentration with respect to the time of adsorption on the as‐prepared Bi2WO6 nanomaterial was measured by UV–visible spectrophotometry according to Beer–Lambert's law. The maximum adsorption capacity was determined by monitoring the change in the adsorption amount of MB in acidic or basic conditions (various pH). The Bi2WO6 nanomaterial showed excellent reusable properties after annealing at 300°C, which was performed to remove the adsorbed MB for recycling.

“…This phenomenon may be explained by that the rise of amount of Bi 2 WO 6 /2 g/L GO will increase the reaction sites that can generate more reactive oxidants. However, the overweight of photocatalysts would increase light scattering and reduce the transmittance, resulting in a decrease in the degradation efficiency of contaminants [20]. From Fig.…”

“…A 500 W xenon lamp (GXZ500, Shanghai, China) with a 420 nm UV-cut filter was utilized as the visible light source. The typical experiment processes were referred to our previous studies [20]. All the samples were immersed in 10 mg/L of RhB (50 mL) aqueous solution.…”

“…However, it is not easy for the Bi 2 WO 6 /GO powder to be separated and recycled from the dye solution during the photocatalysis. In order to overcome these difficulties, some photocatalysts have deposited on textile products to investigate the photocatalytic activity of deposited fabrics in our previous reports such as Bi 2 WO 6 and Bi 2 WO 6 /TiO 2 [20,21]. Up to now, there are no reports about Bi 2 WO 6 /GO composite photocatalysts depositing on textiles for the dye degradation.…”

The environmental repercussions of wastewater from the dye process mean that it is very important to obtain an eco-friendly photocatalyst that would degrade wastewater. Herein, bismuth tungstate/graphene oxide (Bi2WO6/GO) composites are fabricated through in-situ hydrothermal reaction and then the Bi2WO6/GO photocatalysts are deposited onto polyethylene terephthalate (PET) fabric. The obtained Bi2WO6/GO deposited PET fabrics are then characterized through XPS, Raman, SEM, TEM, XRD, UV-vis, BET method and photoluminescence spectroscopy (PL) to investigate their chemical and crystal structures, morphology, optical property, surface area and photochemical properties. Photocatalytic performance is studied through examining the rate of degrading rhodamine B (RhB) under visible light. Surface of PET fibers is densely covered with Bi2WO6/GO. Bi2WO6/GO deposited PET fabrics show a broad absorption band in the visible spectra. Removal rate of RhB on the Bi2WO6/GO deposited PET fabric is the highest with the GO content of 2 g/L (labeled as Bi2WO6/2 g/LGO). The result of active species experiment shows that superoxide radicals (·O2−) plays a major role in the degradation of RhB. Moreover, Bi2WO6/2 g/LGO deposited PET fabric shows excellent cycle stability of photocatalytic degradation for RhB. The findings in this work can be extended to preparation other types of composite on the textile for photocatalysis, which can be applied to remove dyes in the wastewater produced by the textile or leather industry.

In the present work, we designed a mild strategy to make Cu2(OH)PO4 (CHP) nanoparticles on cotton fabrics (CFs) to achieve multi-functionalities. The phytic acid (IP6) assisted method was employed to synthesize nanoparticles (CHP-IP6). Under Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS) as well as thermogravimetric analysis (TGA), we characterized the coated cotton fabrics. The CHP-IP6 treated fabrics showed prominent photocatalytic activity, excellent photocatalytic stability and thorough discoloration of methylene blue (MB) stain under sunlight irradiation.
