Designing
efficient synthesis methodologies, without using expensive
organic structure-directing agents (OSDAs), for industrially important
zeolites is of high significance not only to realize their commercialization
but also to control their structural properties. Herein, we present
a systematic study on seed-directed synthesis of aluminoborosilicate
CON-type zeolites using tetraethylammonium hydroxide (TEAOH) as a
simple OSDA, by particularly focusing on the precise size control
of CIT-1 seeds, which allowed us to improve the overall production
efficiency and to reach the highest solid yield of 38 wt %. It is
revealed that the use of a certain amount of seeds jointly with TEAOH
is the key factor governing the synthesis, where seeds act as growth
centers to promote the crystallization, while TEAOH stabilizes the
structure by charge-compensating with framework atoms. These findings
provide insight into the synthesis of multipore structures from simple
OSDA, which can be further extended to many other systems currently
requiring complex OSDAs.
