Hypothesis: It is a Holy Grail to realize the goal-oriented synthesis of zeotype crystals via direct thermodynamic/kinetic control of crystallization in the simplest inorganic system. Especially, the most commonly used counter cations (i.e.

Herein, we strip nuclei from the synthetic solution and find that high-ordered nucleus (subcrystal) is the premise to ignite high-speed growth of zeolite crystal. The high-ordered subcrystals with the size of only 6-10 nm possess regular aperture structure and microporous area similar to zeolite nanocrystal.

In this work, a green method for the conversion of CO catalyzed by alcohol amines has been developed. Alcohol amines showed considerable activating ability to CO in the cyclization with 2-aminobenzonitrile to quinazoline-2,4(1,3)-dione in water.
