Mesoporous nanocrystal HZSM-5 were successfully synthesized by hydrothermal crystallization during 24 h, at 130 °C with CTAB and TPABr as the templates. The template removing process of as-synthesized sample was studied by TG/DSC. Characterization by modern techniques as XRD, SEM, TEM and TPD-NH3 has showed that the obtained catalyst is highly crystalline with uniformly nanocrystal size. This product...
