美国麦克仪器公司研究人员在《Nature communications》发表文章

近期，苏黎世联邦理工大学化学与生物工程研究所Sharon Mitchell、晶体实验室Ana B. Pinar、粒子物理研究所Paolo Crivelli4、美国麦克仪器公司Jeffrey Kenvin与莱比锡大学Jo¨rgKa¨rger& Javier Pe′rez-Rami′rez在《Nature communications》上共同发表了题为“Structural analysis of hierarchically organized zeolites”的文章。文章中对多级结构分子筛进行了表征，该材料为微孔结晶固体，包含多级孔结构，并有独特的化学性能。此研究借助美国麦克仪器公司气体吸附仪为该项研究提供了准确的材料结构信息。

该项研究中，借助麦克仪器先进的MicroActive软件独有的将压汞法测得的孔径分布与气体吸附法测得的孔径分布进行叠加的功能，得到从微孔到大孔的完整的吸附曲线，并通过高级NLDFT理论计算分子筛的孔径分布，为该项研究提供了强大的数据支持。

该文章的摘要如下：

Advances in materials synthesis bring about many opportunities for technological applications, but are often accompanied by unprecedented complexity. This is clearly illustrated by the case of hierarchically organized zeolite catalysts, a class of crystallinemicroporous solids that has been revolutionized by the engineering of multilevel pore architectures, which combine unique chemical functionality with efficient molecular transport. Three key attributes, the crystal, the pore and the active site structure, can be expected to dominate the design process. This review examines the adequacy of the palette of techniques applied to characterize these distinguishing features and their catalytic impact.
