摘要: Pure-silica-zeolite (PSZ) AST and LTA are synthesized successfully by using the same structure-directing agent (SDA) molecule, but at different concentrations. A dynamic organic SDA is proposed to discuss mechanism of phase discrimination between LTA. Data suggest that molecules can self-assemble into dimer or trimer complexes concentrations π-π interactions, these differences be taken advantage selectively synthesize either PSZ These deviations from Liebau's rules indicate small changes in chemistry, structure, order solution have a great impact on structure selectivity zeolite synthesis.
