In this study, the construction of a highly negatively charged layered material [CH3CH2NH3]6In6S12 (InS-1) by introducing a lacunary cluster as the building block is reported. The pronounced framework negative charge density (5.59 × 10-3) and the soft Lewis basic S component endow InS-1 with an effective ion exchange performance toward heavier Sr2+, with a top-level adsorption capacity qm of 105.35 mg g-1. InS-1 exhibits a good exchange activity over pH 3-12, and the Sr2+-laden product can be facilely eluted.
在本研究中，报道了通过引入缺位簇作为结构单元来构建一种高负电荷层状材料[CH3CH2NH3]6In6S12（InS-1）。显著的骨架负电荷密度（5.59×10-3）和软路易斯碱性硫组分赋予InS-1对较重的Sr2+有效的离子交换性能，其最大吸附容量qm为105.35 mg g-1。InS-1在pH 3-12范围内表现出良好的交换活性，且负载Sr2+的产物能够被轻易洗脱。
