本文介绍了使用氮孔隙法表征金属有机框架,以 UiO-66 为代表材料。

我们的团队专注于合成和表征多孔材料,用于集水、空气净化和二氧化碳捕获等应用。我们真正感兴趣的是了解孔的大小、体积、连通性和化学性质如何影响吸收性能,然后利用这些见解为我们的材料设计工作提供信息。因此,稳健的表征技术至关重要。

表征是任何多孔材料研究的一个重要方面。X 射线衍射、气体吸收技术和热分析技术是表征的顶级方法。这些也可用于研究结构稳定性,这是用于实际应用的任何材料的关键特征。

表面积和孔隙体积是多孔材料的两个最重要的特性。这些特性可以使用市售仪器进行测量,这些仪器使用既定的方法和软件进行操作。氮作为吸收物价格低廉、容易获得且安全。

测量快速可靠。
