Zeolite is widely used as a petrochemical catalyst for the production of raw materials for petroleum and plastic products during crude oil refining. It is a core material whose nanostructure contains tiny holes arranged regularly and repeatedly, and is utilized as ion exchangers and separators. Specifically, these physical chemistry properties are primarily differed by the pole structure that the synthesis of zeolites can bring out the ripple effect in chemical related industries.

Professor Hong Seok-bong (DESE) succeeded in synthesizing PST-14 and a new aluminophosphate molecular, PST-13. The Research team synthesized PST-13 using diethylamine as an organic structure inducing material and then created PST-14, which has never been reported before.

These two molecular sieves are all composed of a basic structure which is the first pair of enantiomer of the zeolite that has small pores in 3D. Shape selectivity exists in that the specific reaction is accelerated or decelerated depending on the geometry of the pores, changing the composition of the product. It means the new zeolite structure can improve the efficiency of commercial processes.
