碳壳限域功能二氧化硅干凝胶实现锂的双模式光学检测与海水回收
Carbon‐Shell‐Confined Functional Silica Xerogels for Concurrent Lithium Dual‐Mode Optical Detection and Seawater Recovery
AI 导读
研究团队开发了一种多功能复合材料，将限域在中空碳球内的二氧化硅干凝胶作为高比表面积基质，杂原子掺杂 CDs 作为荧光标签，共价连接的二苯甲酮衍生配体作为锂结合位点，可同时实现锂提取与光学检测。
推荐理由
该复合材料把锂吸附与荧光检测集成到同一体系，LOD 1.5 nM 与 110 mg g⁻¹ 吸附量给出了检测—提取一体化的性能边界。
创新点
用非荧光受体与基质限域 CDs 耦合实现光学信号转导，把锂吸附与双模式检测集成在同一复合材料中，区别于单独吸附或单独荧光探针的做法。
