A new static hydrothermal method was developed for synthesizing nanosize SAPO-11 molecular sieve.The new method involves aging pretreatment step followed by crystallization process of a precursor gel. The effect of the aging pretreatment on morphology and size of SAPO-11 molecular sieves was investigated. The results of XRD and SEM showed that the aging pretreatment changed the size and morphology...
