Project Description

My research interest lies in the synthesis of zeolite for finding the new zeolite composition potentially usable via many kinds of synthesis approaches for applying in zeolite-catalyzed reactions (ethylene oligomerization. Furthermore, my project also focuses on the selective catalytic reduction (SCR) of nitrogen oxides for automotive emissions control strategy by using zeolites.
