Abstract Metal–organic frameworks (MOFs) are hybrid porous crystalline networks with tunable chemical and structural properties. However, their excellent potential is limited in practical applications by hard‐to‐shape powder form, making it challenging to assemble MOFs into macroscopic composites mechanical integrity. While a binder matrix enables materials, such materials have MOF content thus functionality. To overcome this challenge, nanoMOFs combined tailored same‐charge...
