 Metal organic frameworks, MOFs, are of great interest as potential electrochemically active materials. Few studies have been conducted into understanding whether control of the shape and components of MOFs can optimize their electrochemical performances due to the rational realization of their shapes. We demonstrate a solvothermal method to realize nanostructure engineering of 2D nanoflake MOFs. This article was authored by Huizong Xia, Jianan Zhang, Zhao Yang, and others.
