The project entitled surface effect of Magnesium-Aluminium and Lithium-Aluminium hydrotalcite based adsorbent in hydrogen adsorption which aims to determine the surface effect of modified adsorbent. The adsorbent were synthesized using coprecipitation method while surface modification performed by impregnation method. The adsorbent were characterized using BET Surface Area Analyzer and Field Emission Scanning Electron Microscope (FESEM) for textural properties and surface morphology of the adsorbent. Further, the adsorbent will be analyzed to see the adsorption performances using fixed bed reactor at ambient conditions. Surface effect will be studied applying adsorption studies on different compositional modified adsorbent surface. In this study, hydrotalcite based adsorbent were consisted with magnesium (Mg), lithium (Li) and aluminium (Al) with different molar ratio and later the adsorbent will be modified by palladium (Pd) to activate surface for hydrogen adsorption. The synthesized adsorbent is expected to achieve the optimum hydrogen adsorption capacity as suggested by Department of Energy (DOE)
