Bismuth molybdate photocatalysts were controllably prepared via an electrochemical approach at room temperature. The composition and optical property of each product were determined according to the Na OH and Na 2 MoO 4 quantities in the electrolyte. Pure Bi 3.64 Mo 0.36 O 6.55 was prepared at a Na OH concentration range of 0.2‐0.8 mol L −1 , whereas the Bi 3.64 Mo 0.36 O 6.55 /Bi 14 MoO 24 composite was obtained in an electrolyte containing 0.4 mol L −1 Na OH and 0.5 mol L −1 Na 2 MoO 4 . The results of rhodamine B degradation under visible light indicated that Bi 3.64 Mo 0.36 O 6.55 nanoparticles with a size of 10‐50 nm displayed the best photocatalytic efficiency, which was considerably higher than that of composite one and bulk Bi 3.64 Mo 0.36 O 6.55 .
