| Abstract: Two kinds of bismuth molybdates: α-Bi2Mo3O12 nanotablet and γ-Bi2MoO6 nanoplate were prepared employing mild hydrothermal methods. By tuning the nBi/nMo ratio and pH values, controlled formation of bismuth molybdates can be achieved. Low pH value and high concentration of molybdenum lead to the formation of α-Bi2Mo3O12. High pH value and low concentration of molybdenum favor the formation of γ-Bi2MoO6. Photophysical and photocatalytic studies indicate that γ-Bi2MoO6 nanoplate shows more intense absorption band in the visible light region and better photocatalytic activity than α-Bi2Mo3O12 nanotablet under visible light irradiation. The effect of factors on photocatalytic activities for two kinds of photocatalysts was also discussed. |
