水簇诱导溶胀的互穿 3D COF 实现高效锶捕获
Water-Cluster-Expanded Interpenetrated Covalent Organic Frameworks Create High-Affinity Coordination Microenvironments for Efficient Strontium Capture
AI 导读
研究团队在合成的 3D TB-COF 吸附剂上采用水簇诱导骨架溶胀策略，在模拟核废水中实现 qmax = 346.2 mg g–1 的最大吸附量并保持优异选择性，同时具备突出的耐辐照性。该策略一方面构建由三个相邻网络形成的多源配位微环境以提升对 Sr2+ 的亲和力与选择性，另一方面扩张孔道以降低传质阻力、改善活性位点可及性。实验与理论分析表明，优异的 Sr2+ 识别能力源于水簇调控的配位空间。
推荐理由
原文给出水簇诱导溶胀后 TB-COF 的 qmax 与选择性数据，读者可据此判断互穿 3D COF 吸附锶的潜力。
创新点
针对多重互穿导致配位自由度受限、孔径缩小与传质受阻的问题，用水簇诱导骨架溶胀在互穿 3D COF 中同时扩张孔道并构建三网络协同的配位微环境。
