广东石油化工学院余长林团队报道采用离子交换方法制备了，用于去除染料和苯酚的新型可见光驱动I掺杂Bi₂O₂CO₃纳米片。相关研究成果发表在2024年11月19日出版的国际学术期刊《结构化学》。

该文中，研究人员开发了一种新型的可见光驱动的掺I掺杂Bi₂O₂CO₃纳米片光催化剂，该光催化剂是在室温下通过简单的离子交换路线制备的。这种获得的掺杂I的Bi₂O₂CO₃纳米片显示出几个优点。I0.875-Bi₂O₂CO₃的比表面积是Bi₂O₂CO₃的2.16倍，为降解反应提供了更多的催化位点。

此外，与Bi₂O₂CO₃相比，I0.875-Bi₂O₂CO₃的光电流增强了3.2倍，为降解反应产生了更多的光生电子-空穴对。纹理特性和光电效应之间的协同效应促进了有机污染物的去除。在可见光照射下，I0.875-Bi₂O₂CO₃对甲基橙和苯酚的降解表现出优异的光催化性能。值得注意的是，在I0.875-Bi₂O₂CO₃上照射60分钟，苯酚降解率达到88%，约为Bi₂O₂CO₃的29倍。

该发现可能为开发一种有前景的I掺杂催化剂，去除有机污染物提供了机会。

Abstract: Here, we developed a novel visible-light-driven I- doped Bi2O2CO3 nano-sheet photocatalyst fabricated via a facile ion exchange route at room temperature. This obtained Bi2O2CO3 nano-sheets with I- doping showed several advantages. The specific surface area of I0.875-Bi2O2CO3 was 2.16 times higher than that of Bi2O2CO3, providing more catalytic site for degradation reactions. Moreover, a 3.2 times photocurrent enhancement was observed in I0.875-Bi2O2CO3 comparing with Bi2O2CO3, producing more photogenerated electron-hole pairs for degradation reactions. The synergistic effect between texture property and photoelectric effect boosted the removal of organic pollutants. Under visible light illumination, I0.875-Bi2O2CO3 displayed superior photocatalytic performance for degradation of methyl orange and phenol. Notably, a phenol degradation rate of 88% was achieved over I0.875-Bi2O2CO3 with illuminating for 60 min, which was about 29 times higher than Bi2O2CO3. This finding may provide an opportunity to develop a promising I- doped catalyst for organic pollutants removal.
