A dual role as a support and a source of Al is played by the alumina substrate in an ionothermal method for ambient‐pressure synthesis of aluminophosphate molecular sieve membranes through substrate‐surface conversion (see picture; IL: ionic liquid, SDA: structure‐directing agent). Aluminophosphate membranes with CHA, AEL, AFI, and LTA structure types could be obtained.
