摘要:

Two kinds of bismuth molybdates: α-Bi 2Mo 3O 12 nanotablet and γ-Bi 2MoO 6 nanoplate were prepared employing mild hydrothermal methods. By tuning the n Bi/n Mo 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-Bi 2Mo 3O 12. High pH value and low concentration of molybdenum favor the formation of γ-Bi 2MoO 6. Photophysical and photocatalytic studies indicate that γ-Bi 2MoO 6 nanoplate shows more intense absorption band in the visible light region and better photocatalytic activity than α-Bi 2Mo 3O 12 nanotablet under visible light irradiation. The effect of factors on photocatalytic activities for two kinds of photocatalysts was also discussed.
