Structurally sound : The synthesis of AlPO 4 ‐LTA zeolite in ionic liquids employs 1‐benzyl‐3‐methylimidazolium, tetramethylammonium, and fluoride ions for structuring α cages, sodalite cages, and cubes (see picture; C gray, N blue, O red, Al and P purple, F green). Selective removal of 1‐benzyl‐3‐methylimidazolium ions results in a stable AlPO 4 ‐LTA molecular sieve. The α cages of AlPO 4 ‐LTA framework can be evacuated while maintaining structural integrity.
