Shape-controlled synthesis of metal – organic frameworks with adjustable Fenton-like catalytic activity

Controllable synthesis of metal–organic frameworks with well-defined morphology, composition, and size is of great importance toward understanding their structure–property relationship in various applications. Herein, we demonstrate a general strategy to modulate the relative growth rate of the seco...
