Abstract

The objective of this study is to improve the hydrogen desorption temperature and the hydrogen desorption capacity. The material preparation was done through mechanical alloying technique. In this method, the milling of the material was carried out within 5 hours, 10 hours and 15 hours, ball to powder ratio was 10:1. The catalyst was inserted by 10 wt%SiC. From XRD measurements revealed that the sample was successfully reduced to a nanocrystalline scale. The phase MgH2 as the main phase, and followed by Ni and SiC phase as the minor phase. The microscopy observation with SEM showed the irregular particle shape, the particle size in the sample is not homogeneous because of the agglomeration effect during milling. The hydrogen release capacity was obtained in the samples which were milled for 10 hours at the weight of 5 wt% Ni-SiC catalyst with release of 2.6 wt% within 16 minutes.
