One-step synthesis of nitrogen-grafted copper-gallic acid for enhanced methylene blue removal

Abstract Nitrogen-grafting through the addition of glycine (Gly) was performed on a metal- phenolic network (MPN) of copper (Cu2+) and gallic acid (GA) to increase its adsorption capacity. Herein, we reported a one-step synthesis method of MPN, which was developed according to the metal–ligand compl...
