In this method reaction times decreases with many more advantages (like low costs, quantitative yields, without using any organic solvent). We also found derivatives of 5-substituted 1H- tetrazole with good to impressive yields (90–97%). In the present experimentation synthesized zeolite is characterized by using techniques like X-ray diffraction (XRD), scanning electronic microscopy (SEM), and Fourier transform-infrared (FT-IR spectroscopy) and catalyst is separated by simple filtration and washed with appropriate solvents without loss of any catalytic activity.
