摘要：
Continuous, multilayered ZSM-5 zeolite films have been grown by direct synthesis on cordierite modules. The influence of the H2O/SiO2 ratio used in the synthesis mixture on the film properties was studied by inspecting the film formed in the external module surface at several water contents. It is shown that dilution prevents the film to become dense, modifies zeolite crystal morphology and reduces markedly the crystallization of zeolite into a non-adhered powder form.
