in several organocationic reactions in which textural and acid–baseproperties were dependent on a number of variables such as aluminum salt, precipitating agent, or calcination temperatures [ 3 – 7 ]. Thus, in the last few years many works have

. Scanning electron microscopy (SEM) was employed to study the morphology and crystallite size of zeolites. The SEM images were recorded over a Hitachi S-800 electron microscope operated at 5 kV. The acid–baseproperty of zeolite was characterized by having

Certainly, the latter
