(4) 提出了掺杂稀土金属离子改性铋基光催化剂的可行性机理。

中文摘要

虽然Bi₂MoO₆(BMO)近年来受到广泛关注，但由于其光响应范围有限，电荷分离效率低，其可见光光催化活性仍然较差。本文采用水热法制备了一系列可见光驱动的Y³⁺掺杂BMO (Y-BMO)光催化剂。可见光照射下，Y-BMO对罗丹明B和刚果红有机污染物的最佳降解率分别是纯BMO的4.3倍和5.3倍，且经过4次循环实验，Y-BMO的降解效率没有明显下降。由于Y³⁺的掺杂，BMO的晶体结构由较厚的层状结构转变为较薄的花状结构，导致其比表面积增大；X射线光电子能谱显示，O 1s轨道在531.01和530.06 eV处存在高强度峰，证实了Y-BMO中氧空位的形成；光致发光和电化学阻抗谱测量表明，复合材料的发光强度和界面电阻显著降低，说明Y³⁺掺杂大大抑制了电子–空穴对的复合。由此，使得Y-BMO具有了较高的光催化活性。本研究为通过掺杂稀土金属离子制备高效铋基光催化剂来获得高的光催化性能提供了一条有效途径。

Preparation of Y³⁺-doped Bi₂MoO₆ nanosheets for improved visible-light photocatalytic activity: Increased specific surface area, oxygen vacancy formation and efficient carrier separation

Abstract

Abstract

Although Bi₂MoO₆ (BMO) has recently received extensive attention, its visible-light photocatalytic activity remains poor due to its limited photoresponse range and low charge separation efficiency. In this work, a series of visible-light-driven Y³⁺-doped BMO (Y-BMO) photocatalysts were synthesized via a hydrothermal method. Degradation experiments on Rhodamine B and Congo red organic pollutants revealed that the optimal degradation rates of Y-BMO were 4.3 and 5.3 times those of pure BMO, respectively. The degradation efficiency of Y-BMO did not significantly decrease after four cycle experiments. As a result of Y³⁺ doping, the crystal structure of BMO changed from a thick layer structure to a thin flower-like structure with an increased specific surface area. X-ray photoelectron spectroscopy showed the presence of high-intensity peaks for the O 1s orbital at 531.01 and 530.06 eV, confirming the formation of oxygen vacancies in Y-BMO. Photoluminescence (PL) and electrochemical impedance spectroscopy measurements revealed that the PL intensity and interface resistances of composites decreased significantly, indicating reduced electron–hole pair recombination. This work provides an effective way to prepare high-efficiency Bi-based photocatalysts by doping rare earth metal ions for improved photocatalytic performance.
