Abstract
Zeolite films with diverse microstructures were prepared from highly regular seed monolayers by accurate manipulation of various synthetic parameters during secondary growth The effects of the hydrothermal pretreatment procedure hydrothermal pretreatment temperature and duration secondary growth temperature and duration of prepared zeolite films on final microstructures were investigated in detail Based on these results a mechanism was proposed to elucidate the effects of hydrothermal pretreatment on the secondary growth dynamics of the zeolite films hydrothermal pretreatment could induce the separation of secondary nucleation and the subsequent growth process Consequently the disordered growth of zeolite films could be effectively avoided
