  The nano-beta zeolite was synthesized by microwave method and characterized by X-ray powder Diffraction (XRD), X-ray Fluorescence (XRF), Brunauer?Emmett?Teller (BET), Scanning Electron Microscopy (SEM) and Dynamic Light Scattering (DLS) techniques. In all of the samples, the gel of nano-beta zeolite was prepared at room temperature (20°C) and the gel crystallization was performed in the microwave at different heating period and temperatures. The crystallization percentage of fabricated nano-beta zeolite was determined by XRD pattern. The particle size was calculated by SEM method then verified by DLS method. At the optimum synthesis condition, the Si/ Al ratio and effective surface of nano-beta zeolite were determined by XRF and BET tests, respectively. The results showed that the zeolite crystals start to grow up after 180 minutes crystallization at the lowest temperature, 60°C, with th.. View More»
