近期，蘇黎世聯邦理工大學化學與生物工程研究所Sharon Mitchell、晶體實驗室Ana B. Pinar、粒子物理研究所Paolo Crivelli4、美國麥克儀器公司Jeffrey Kenvin與萊比錫大學Jo¨rgKa¨rger& Javier Pe′rez-Rami′rez在《Nature communications》上共同發表了題為“Structural analysis of hierarchically organized zeolites”的文章。文章中對多級結構分子篩進行了表征，該材料為微孔結晶固體，包含多級孔結構，并有獨特的化學性能。此研究借助美國麥克儀器公司氣體吸附儀為該項研究提供了準確的材料結構信息。

該項研究中，借助麥克儀器先進的MicroActive軟件獨有的將壓汞法測得的孔徑分布與氣體吸附法測得的孔徑分布進行疊加的功能，得到從微孔到大孔的完整的吸附曲線，并通過高級NLDFT理論計算分子篩的孔徑分布，為該項研究提供了強大的數據支持。

該文章的摘要如下：

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.
