“…Without NaOH, the alkaline environment provided by 1.0 mol L −1 Na 2 MoO 4 favored the generation of Bi 2 O 3 according to Equation . The Bi 2 O 3 film was broken down, and intermittent discharges and weak sparks were generated, affording energy to initiate Reaction . Consequently, cubic Bi 3.64 Mo 0.36 O 6.55 (JCPDS No.…”

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 NaOH and Na2MoO4 quantities in the electrolyte. Pure Bi3.64Mo0.36O6.55 was prepared at a NaOH concentration range of 0.2‐0.8 mol L−1, whereas the Bi3.64Mo0.36O6.55/Bi14MoO24 composite was obtained in an electrolyte containing 0.4 mol L−1 NaOH and 0.5 mol L−1 Na2MoO4. The results of rhodamine B degradation under visible light indicated that Bi3.64Mo0.36O6.55 nanoparticles with a size of 10‐50 nm displayed the best photocatalytic efficiency, which was considerably higher than that of composite one and bulk Bi3.64Mo0.36O6.55.

Bismuth vanadate compounds including BiVO4, Bi25VO40, and the composite Bi25VO40/Bi7V11O9 with photocatalytic properties were firstly synthesized via a facile electrochemical strategy. The amount of NaOH in the electrolyte and electric currents were discovered to be crucial variables to the composition, morphology, and crystallinity of the products. Monoclinic phase BiVO4 and Bi25VO40 with sillenite structure can be obtained at 2 A with NaOH concentration of 0–10−4 and 0.1–0.4M, respectively. The acquirement of Bi25VO40/Bi7V11O9 can be achieved with electric current 3–5 A in an electrolyte containing 0.4M NaOH. All the electrosynthesized samples exhibit good visible‐light‐driven photocatalytic activity in the degradation of rhodamine B, much higher than that of the commercial TiO2 (P25).
