Abstract

A multi-modal platform enabling simultaneous impedance spectroscopy and X-ray scattering is presented. When applied to zeolite crystallization, four-electrode impedance measurements reliably track bulk crystallization kinetics in agreement with X-ray diffraction, while two-electrode impedance data reveal artefacts from electrode passivation.

摘要

本文介绍了一种能够同时进行阻抗谱和X射线散射的多模态平台。当应用于沸石结晶过程时，四电极阻抗测量能够可靠地追踪整体结晶动力学，与X射线衍射结果一致，而两电极阻抗数据则揭示了电极钝化产生的假象。
