Abstract
The newly synthesized ternary system are consisting of metallic-Mg-ions diffused in hollow carbon nano-spheres (HCNS) that embedded with platinum nano-particles (NP). The ternary system exhibits characteristics features in hydrogen release. It is expected to be superior and efficient as hydrogen carrier to be used for energy release applications. The synthesized Mg/HCNS/Pt ternary system was well characterized by both of XRD and 3D-AFM. The measured H-2-desorption capacities were promising values recording 6.78, 6.92, 7.05 and 7.85 wt% at temperatures 270, 300, 330 and 370 degrees C respectively. These results confirmed that MgH2-storage capacity was enhanced and reinforced by extraordinary BET surface area of 1810 m(2)g(-1) attributable to (HCNS + Pt-NP + Mg - NP). The kinetics of desorption results indicated that Mg/HCNS/Pt composite can release hydrogen 7.85 wt% at 370 degrees C in 1.42 min (85.2 s) and minimum desorption capacity observed was 6.78 wt% at 270 degrees C in 2.8 min (168 s).
