Metal-organic frameworks (MOFs) have attracted considerable attention as novel nanoporous materials that combine the properties of organic and inorganic porous materials. HKUST-1 is one of the most well-developed and representative MOFs with wide applications in gas storage and separation, adsorption, and capture. In this study, we used microfluidics, an advanced technique of manipulation of small fluid volumes in microscale or even nanoscale channels, to investigate the effect of sodium dodecyl sulfate (SDS) on the growth of HKUST-1 crystals. We directly observed the morphological evolution of HKUST-1 crystals through droplet arrays with the SDS concentration gradient. The morphology of HKUST-1 evolved from cubic to cuboctahedron and finally to octahedron with increasing SDS concentration. The study results demonstrated the important role played by anions in solution in the structural regulation of HKUST-1.

添加剂对浓度梯度微流控芯片合成的HKUST-1晶体生长的影响。

金属有机骨架(MOF)作为结合了有机和无机多孔材料特性的新型纳米多孔材料已经引起了广泛的关注。HKUST-1是最先进的MOF之一,在气体存储,分离,吸附和捕获方面具有广泛的应用。在这项研究中,我们使用微流控技术(一种在微尺度甚至纳米尺度的通道中处理少量流体的先进技术)来研究十二烷基硫酸钠(SDS)对HKUST-1晶体生长的影响。我们通过具有SDS浓度梯度的液滴阵列直接观察了HKUST-1晶体的形态演变。随着SDS浓度的增加,HKUST-1的形态从立方演化为立方八面体,最后发展为八面体。
