Controllable Growth of Bi2MoO6 Nanoplates by Citric Acid Assisted Hydrothermal Process and Their Photocatalytic Properties
Tianjin Medical College, Tianjin 300222, P.R.China
Bi2MoO6 nanoplates with different sizes have been controllably fabricated by citric acid (CA) assisted hydrothermal process. The effects of CA on the morphology of Bi2MoO6 nanoplates have also been investigated. It is found that CA has a critical role in the crystallinity and size of Bi2MoO6 nanoplates. On the basis of XRD analysis and SEM observation of the products, the mechanism for CA assisted hydrothermal synthesis of the Bi2MoO6 nanoplates is discussed. The photocatalytic activity of as-prepared Bi2MoO6 was evaluated by the degradation of RhB dye in water, and the sample prepared when the amount of CA was 2.5mmol exhibited the highest photocatalytic activity.
Key words: Bi2MoO6 / hydrothermal process / citric acid
