A membrane includes a first layer, and a second layer coupled to the first layer. The second layer includes a network of catalytic sites, each catalytic site having a catalytic center characterized by promoting a chemical reaction of a target material. A method of forming a chemically reactive membrane includes applying a first solution to a structure, the first solution includes a macrocyclic ligand having electron-donating ligands and a side functional group for crosslinking, crosslinking a plurality of the macrocyclic ligand to form a first network of crosslinked macrocyclic ligands, and applying a second solution to the structure, the second solution comprising a catalytic center. Each catalytic center complexes with the electron-donating ligands of each macrocyclic ligand to form catalytic sites in the first network of crosslinked macrocyclic ligands.

Described herein is a simple and versatile synthetic strategy for the preparation of metal-organic frameworks comprising a carbon matrix doped with nitrogen atoms, wherein transition metal ions are bonded to the carbon matrix via the nitrogen atoms.
