Abstract
Heterostructured CdS/Bi2MoO6 nanocomposite was prepared based on Bi2MoO6 framework assembled from nanoflakes through a two-step facile approach. Photocatalytic activity of the as-synthesized product toward Cr (VI) reduction was studied. The heterostructured CdS/Bi2MoO6 nanocomposite shows a much higher photocatalytic activity in the reduction of Cr (VI) to Cr (III) than pure Bi2MoO6, and the reduction ratio of Cr (VI) can reach 94.6% in 15 min. The superior photocatalytic reduction activity of the heterostructured nanocomposite was ascribed to the enhanced visible light absorption ability and dramatically boosted separation efficiency of charge carriers.
