| 英文摘要 | BiVO4, a promising visible-light responding photocatalyst, has aroused extensive research interest because of inexpensiveness and excellent chemical stability. However, its main drawback is the poor photoinduced charge-transfer dynamics. Building nanostructures is an effective way to tackle this problem. Herein, we put forward a new method to prepare nanostructured BiVO4 from Bi-based metal-organic frameworks[Bi-MOF(CAU-17)] precursor. The as-prepared material has a rod-like morphology inherited from the Bi-MOF sacrificial template and consists of small nanoparticle as building blocks. Compared with its counterparts prepared by conventional methods, MOF-derived nanostructured BiVO4 shows better light absorption ability, narrower bandgap, and improved electrical conductivity as well as reduced recombination. Consequently, BiVO4 nanostructure demonstrates high photocatalytic activity under visible light towards the degradation of methylene blue. Methylene blue can be degraded up to 90% within 30 min with a reaction rate constant of 0.058 min(-1). Moreover, the cycling stability of the catalyst is excellent to withstand unchanged degradation efficiency for at least 5 cycles. |
