Bi2MoO6/(BiO)2CO3 heterojunction photocatalysts were synthesized via a facile hydrothermal route. It is found that introduced Bi2MoO6 can turn morphology of (BiO)2CO3 crystal and restrict growth of crystalline grain by changing Bi2MoO6 loadings. When Bi2MoO6 loading is lower, Bi2MoO6 can preferentially adhere on side of {001} crystal facet of (BiO)2CO3, which inhibit the growth rates in lateral orientation of {001} crystal facets and subsequently cause the preferentially growth in [001] orientation. With further increase of Bi2MoO6 loading, Bi2MoO6 nanoparticles can cover entire surface of (BiO)2CO3 crystal, which restrict largening of crystalline grain. The resulting Bi2MoO6/(BiO)2CO3 heterostructured photocatalysts exhibited higher activity for KN-R photo-degradation under artificial solar light.
