Synthesis of Anionic Metal-Organic Zeolites for Selective Gas Adsorption and Ion Exchange.

We report here a new method to construct metal-organic zeolites (MOZs) via the mixing of dicarboxylic acid and tetrazole ligands. Two anionic MOZs, MOZ-200 and MOZ-201 with BCT and ATN topologies, were developed successfully by this approach and exhibit high selective CO2 uptake and Ln3+ ion exchange.
