| 英文摘要 | A Bi(OH)(3) precursor was prepared using a precipitation method using bismuth nitrate as a starting material and ammonia as the precipitation agent. Bi(OH)(3) was then calcined at different temperatures and different time. X-ray diffraction (XRD), Raman spectroscopy, thermogravimetry (TG), scanning electronic microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS) were used to investigate the phase transformation from Bi(OH)(3) to Bi2O3 and the particle size, morphology, and optical properties of Bi2O3 during the phase transformation. It was found that Bi(OH)(3) after calcination undergoes the following process: Bi(OH)(3) -> Bi5O7NO3 -> beta-Bi2O3/Bi5O7NO3 -> beta-Bi2O3/Bi5O7NO3/alpha-B2O3 -> alpha-Bi2O3. It was observed that the above phase transformation from Bi(OH)(3) to Bi2O3 and the growth of the particle size are interrelated. It was also found that the phase transition from beta-Bi2O3 to alpha-Bi2O3 was faster compared with the phase transition from Bi5O7NO3 to beta-Bi2O3. Also, the degradation of Rhodamine B (RhB) was studied to investigate and compare the photocatalytic performance of Bi2O3 with different crystalline phases. The result indicates that Bi5O7NO3 and beta-Bi2O3 exhibit excellent photocatalytic performance, while alpha-Bi2O3 has a low photocatalytic activity. |
