Summary:Hydrogen is considered to be the most promising clean and environmentally friendly energy carrier capable of fulfilling the future energy needs. In vehicular applications, the use of hydrogen emits water vapor as the only by-product. However, in addition to green hydrogen production, hydrogen storage is presently considered to be the crucial issue for empowering the “Hydrogen-economy”. Recently, microporous materials have gained enthusiastic research interest for gas storage applications owing to their potential applications in industries and commercial products. Here, we have investigated the high-pressure hydrogen adsorption behaviour of two NIST reference zeolite X, zeolite Y and zeolite ZSM-5 materials at room temperature and at liquid nitrogen temperature. The structure and microstructure analysis of the samples were analyzed through XRD, TEM and SEM. Among the three NIST reference zeolites investigated, zeolite Y exhibits high hydrogen uptake characteristics. The comparative hydrogen adsorption isotherms of three NIST reference zeolites will be described and discussed in detail.
