A novel visible‐light‐driven nano‐Bi 2 MoO 6 /calcined mussel shell (CMS) photocatalyst composite was designed and synthesised by a facile hydrothermal method and characterised by X‐ray diffraction, Fourier‐transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, high‐resolution transmission electron microscope and UV–vis diffuse reflectance spectroscopy. The photocatalytic activity of the as‐prepared samples was evaluated by photocatalytic degradation of Rhodamine B (RhB) under visible‐light ( λ > 420 nm) irradiation. The results indicated that 5% nano‐Bi 2 MoO 6 /CMS photocatalysts composite exhibited the highest activity, and its RhB degradation efficiency reached 98.7% within 60 min, which was 1.2 times higher than that of the pure Bi 2 MoO 6 photocatalyst. This work demonstrated that CMS powder could be utilised to fabricate Bi 2 MoO 6 /CMS photocatalyst nanocomposites for water‐treatment applications and this study could provide a solution to the abandoned mussel shell resources from waste and environmental pollution.
