The first discovery of aluminophosphate (AlPO4) molecular sieve was reported by Wilson et al[1] in 1982. Since then, the successful incorporation of other metal and/or nonmetal cations into the framework structure of AlPO4 molecular sieve has resulted in the generation of metal aluminophosphate (MeAPO) and metal silicoaluminophosphate (MeAPSO) molecular sieves[2～5].
