Modification of zeolite-Y templated carbon at various nitrogen loading for hydrogen adsorption

The purpose of this research is to modify the zeolite-Y templated carbon (ZTC) at various nitrogen loading in the amount of 5, 10 and 15 mL, using acetonitrile as nitrogen precursor. ZTC then was prepared by three main steps, namely impregnation, carbonization and removal of the template. ZTC was characterized with physical adsorption of N2 (BET) which showing the optimum surface area at 1665.59 m2/g for ZTC-Nitrogen 5 mL variation. This result is comparable with the adsorption capacity of hydrogen at the room temperature under 1 bar pressure. Adsorption capacity of hydrogen gas in ZTC-Nitrogen 5, 10 and 15 mL were 3.85, 3.08 and 2.10 % (w), while the desorption was 15.07, 86.59 and 75.00 % (w).
