Controllable fabrication of Fluorite-type Bi4MoO9 nanocrystals with well-defined octahedral shape for visible-light photocatalytic degradation
Source abstract
Abstract
The Fluorite-type Bi 4MoO 9 nanocrystals with well-defined octahedral shape were successfully synthesized via a facile hydrothermal route. The structural transformation from the Aurivillius-type Bi 2MoO 6 nanocrystals to the Fluorite-related nanocrystals (Bi 4MoO 9) can be efficiently and precisely controlled by regulating the pH value of the reaction. The influences of reaction time and temperature were investigated to gain a deep understanding of the formation process of octahedral-shaped Bi 4MoO 9. Furthermore, the photocatalytic activity results showed that the octahedral Bi 4MoO 9 single crystals manifested excellent photocatalytic activities for the degradation of tetracycline (TC), rhodamine B (RhB), and bisphenol A (BPA). Additionally, the possible degradation intermediates of TC were unraveled and the ecotoxicity changes of identified TC intermediates were evaluated in detail. This present study develops a novel morphology structure of Bi 4MoO 9 and highlights its promise in the field of environmental remediation.
