The Bi 2 WO 6 nanosheets have been synthesized at different pH values by a hydrothermal method. Various characterization techniques, such as X‐ray diffraction (XRD), scanning electron microscopy (SEM), UV/Vis absorption spectra and contact angle (CA) analysis, were employed to investigate the as‐prepared products. The Bi 2 WO 6 nanosheets prepared at pH = 9 (BW9) showed excellent photocatalytic performance by degradation of the methylene blue (MB) solution (10 mg/L) and the degradation rate was found to be 93 % under visible light for 3 h. Furthermore, the wettability of the as‐synthesized Bi 2 WO 6 film was studied by measuring the water CA. It was found that they show extraordinary superhydrophobicity and excellent adhesion of water, even without modification by low‐surface‐energy materials.
