The yolk-shell structure Bi(4-2x)Mo(x)O6 (x⩽1) microspheres were successfully synthesized via a simple solvothermal method. The morphology, structure and photocatalytic performances of the samples in the degradation of rhodamine B (RhB) and methyl orange (MO) were characterized by X-ray photoelectron spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, UV-vis absorption spectroscopy and electrochemical impedance spectra, respectively. The results show that the yolk-shell structure Bi(2.38)Mo(0.81)O6 microspheres exhibit the best photocatalytic performance for the degradation of RhB and MO with a degradation rate of 99% and 72% under visible light irradiation.
通过一种简单的溶剂热法成功合成了蛋黄壳结构的Bi(4 - 2x)Mo(x)O6（x⩽1）微球。分别采用X射线光电子能谱、扫描电子显微镜、透射电子显微镜、X射线衍射、紫外可见吸收光谱和电化学阻抗谱对样品在降解罗丹明B（RhB）和甲基橙（MO）中的形貌、结构和光催化性能进行了表征。结果表明，蛋黄壳结构的Bi(2.38)Mo(0.81)O6微球在可见光照射下对RhB和MO的降解表现出最佳的光催化性能，降解率分别为99%和72%。
