Abstract

Prenucleation clusters: in situ synchrotron X-ray scattering with a one-second time resolution revealed the occurrence of nano-sized clusters during the nucleation and early growth of nanocrystals of a zeolitic imidazolate framework (ZIF). The complex crystallization process exhibits similarities with crystallization processes of zeolites from solution. Hmim= 2-methylimidazole.

摘要

成核前簇

利用 1 秒时间分辨率的同步辐射 X 射线散射，在沸石咪唑酯骨架（ZIF）纳米晶体的成核和早期生长过程中发现了纳米级簇的存在。这一复杂的结晶过程与溶液中沸石的结晶过程具有相似性。Hmim=2-甲基咪唑。
