Abstract

Abstract : A leaf-like ZIF-L-Co is synthesized for the first time and the molar ratio of Hmim/Co plays an important role in the synthesis. ZIF-L-Co is a transient phase at the initial stage of ZIF-67 crystal growth. The crystallization process of ZIF-67 from ZIF-L-Co follows a solid transformation mechanism. Abstract : A novel Co-containing zeolitic imidazolate framework with a leaf-like morphology (ZIF-L-Co) was synthesized in aqueous media and proved to be the transient phase in the formation of ZIF-67. The phase and morphology of the products could be tailored by changing the concentration and molar ratio of the reagents. Our study herein provides a new insight into the crystal growth of ZIFs.
