近期，蘇黎世聯(lián)邦理工大學(xué)化學(xué)與生物工程研究所Sharon Mitchell、晶體實(shí)驗(yàn)室Ana B. Pinar、粒子物理研究所Paolo Crivelli4、美國(guó)麥克儀器公司Jeffrey Kenvin與萊比錫大學(xué)Jo¨rgKa¨rger& Javier Pe′rez-Rami′rez在《Nature communications》上共同發(fā)表了題為“Structural analysis of hierarchically organized zeolites”的文章。文章中對(duì)多級(jí)結(jié)構(gòu)分子篩進(jìn)行了表征，該材料為微孔結(jié)晶固體，包含多級(jí)孔結(jié)構(gòu)，并有獨(dú)特的化學(xué)性能。此研究借助美國(guó)麥克儀器公司氣體吸附儀為該項(xiàng)研究提供了準(zhǔn)確的材料結(jié)構(gòu)信息。

該項(xiàng)研究中，借助麥克儀器先進(jìn)的MicroActive軟件獨(dú)有的將壓汞法測(cè)得的孔徑分布與氣體吸附法測(cè)得的孔徑分布進(jìn)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(jí)NLDFT理論計(jì)算分子篩的孔徑分布，為該項(xiàng)研究提供了強(qiáng)大的數(shù)據(jù)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.
