通过引入表面活性剂（PEG6000、PEG20000、PVP-K30、CTAB、氢氧化四乙铵），采用简便的低温溶液结晶方法，成功制备了稳定的γ-Bi2O3。使用 XRD 和 SEM 来表征 Bi2O3 样品的相变和形貌。结果发现，随着反应时间的增加，本研究中使用的表面活性剂通过阻止 γ-Bi2O3 向 α-Bi2O3 的转变，在稳定 γ-Bi2O3 方面发挥着关键作用。而且，上述表面活性剂对γ-Bi2O3的粒径和形貌没有明显影响。 RhB的光催化降解结果表明，稳定的γ-Bi2O3比α-Bi2O3具有更高的光催化活性。
Stable γ-Bi2O3 was successfully prepared through the introduction of a surfactant (PEG6000, PEG20000, PVP-K30, CTAB, Tetraethylammonium hydroxide) in a facile solution crystallization method at low temperature. XRD and SEM were used to characterize the phase transformation and morphology of the Bi2O3 samples. It is found that the surfactant used in this study plays a key role in stabilizing γ-Bi2O3 by prohibiting the transition from γ-Bi2O3 to α-Bi2O3 as the reaction time increases. Moreover, these above surfactants have no obvious effect on the particle size and morphology of γ-Bi2O3. Photocatalytic degradation of RhB results show that stable γ-Bi2O3 has a higher photocatalytic activity than α-Bi2O3.
