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 (20C) 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, 60C, with the microwave method. Nano particles size of zeolite which are calculated by XRD then validated by DSL and SEM methods were between 100-200 nm. The specific surface area of the fabricated samples from BET adsorption was determined to be 632 m 2 /gr.
