摘要:
The present invention is a method that perturbs the initial crystallization of a material from a less desired phase into a more desired phase. More specifically, the present invention is a method to form a different crystallization of a zeolite, mesoporous material, SAPO4, AlPO4 or porous inorganic oxide after the hydrothermal synthesis has started and a precursor crystalline phase has formed.
