Environmentally friendly synthesis of flexible MOFs M(NA)2(M = Zn, Co, Cu, Cd) with large and regenerable ammonia capacity

Two environmentally friendly and efficient synthesis methods, NH₃-assisted synthesis and solvent-evaporated conversion, have been developed for the synthesis of M(NA)₂(M = Zn, Co, Cu, Cd) flexible MOFs with recyclable NH₃adsorption.
