[Abstract] The development of zeolitic coatings has attracted the attention because of the specific properties of these materials. The coating on different surface can contribute to solving the problems related to classical zeolite catalyst, such as powder crystals, microgranules and pellets. The zeolite coatings improve the mass transfer, low pressure and flow patterns. For these reasons in the present work, we studied the zeolite coating formation on glass sphere. The effect of physical and chemical modification of the substrate on zeolite coating formation was evaluated. The glass spheres were grinding using SiC paper and then they were soaked in a polyelectrolyte solution (PDDA, APS, or PEI). Afterward, the modified spheres were submitted to hydrothermal treatment using a batch composition 0.0257K2O: 0.0146 Na2O: 0.0146Al2O3: 0.0557SiO2: 0.829H2O at 448 K for 24 h. According to XRD results, the coating formed on the functionalized sphere corresponded to merlinoite and philipsite phases. It was found that the pretreatment of the spheres enhances the formation of a homogeneous zeolite coating with improved textural properties compared to the coating obtained on the glass sphere without previous treatment. These properties make these materials useful for adsorption and catalytic processes.
