Abstract
Kenaf fiber has been recognised as a new material for adsorption based on its porous structure. However, previous studies have proved that modified kenaf could give better interaction towards adsorbates than the raw kenaf during the adsorption. In this study, kenaf core fiber has been modified using Nickel metal (Ni-metal). Different concentration of Nickel nitrate, Ni(NO3)2(0.01 M and 1 M) have been used to observe the effect of Ni-metal for hydrogen adsorption. Initially, raw kenaf sample has been grinded and sieved into 500 µm in size. Then, the sample was heated to remove the moisture and Ni(NO3)2has been added into the dried kenaf. Based on this study, modified kenaf with 0.1 M Ni(NO3)2and 1 M Ni(NO3)2has adsorbed more hydrogen compared to the raw kenaf. The result has provided a fundamental knowledge of kenaf as hydrogen storage material.
