| Resumo: | Due to the growing adhesion of large companies and urban homes to photovoltaic energy, the demand for solar panels has increased simultaneously. With this increase, the amount of waste that is produced along with the photovoltaic panels also increases. However, there is no ecologically viable destination for the waste. In view of this, in this project a residue composed mainly of silicon dioxide was used, supplied by the company LIASA. The residue was previously characterized with X Ray diffraction (XRD) X Ray Fluorescence (XRF), Zeta potential and Scanning electron microscopy analyzes to identify its structure. After knowing the structure of the material, synthesis methods were studied, adjusting parameters such as molar ratio of Na2O/SiO2 and crystallization time to obtain the zeolites LTA and faujasite NaX, which were characterized by XRD, Textural analysis and Scanning electron microscopy comparing the results obtained with the standard zeolites. After the characterization, the usability of the residue was concluded as an alternative source of silicon for eco-friendly synthesis of zeolites. |
