Abstract Nanosized Ag 2 O decorated Bi 2 MoO 6 hierarchical microspheres were successfully prepared and evaluated as efficient visible-light-responsive photocatalysts. X-ray diffraction (XRD) patterns confirmed that the formation of the Ag 2 O and Bi 2 MoO 6 composites while scanning electron microscopy (SEM) and energy dispersive X-ray spectrometer (EDX) results revealed the relatively uniform deposition of Ag 2 O nanoparticles on the surface of Bi 2 MoO 6 microspheres. The visible light photocatalytic activity of the composites was studied by photodegradation of methyl orange (MO) and the composite with Ag to Bi ratio of 1: 1 shows the highest activity due to the effective separation of photocarriers. The photocatalytic mechanism study indicates photogenerated holes play a key role for the dye degradation.
