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 H2-desorption capacities were promising values recording 6.78, 6.92, 7.05 and 7.85 wt% at temperatures 270, 300, 330 and 370 °C respectively. These results confirmed that MgH2-storage capacity was enhanced and reinforced by extraordinary BET surface area of 1810 m2 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 °C in 1.42 min (85.2 s) and minimum desorption capacity observed was 6.78 wt% at 270 °C in 2.8 min (168 s).

用于超高性能储氢的过饱和金属镁离子扩散中空碳纳米球/铂

摘要 新合成的三元系统由金属-Mg 离子组成，这些离子扩散在嵌入铂纳米颗粒 (NP) 的空心碳纳米球 (HCNS) 中。三元体系在氢释放方面表现出特征。预计作为用于能量释放应用的氢载体是优越和高效的。合成的 Mg/HCNS/Pt 三元体系通过 XRD 和 3D-AFM 得到了很好的表征。在 270、300、330 和 370 °C 的温度下，测得的 H2 解吸能力是有希望的值，分别为 6.78、6.92、7.05 和 7.85 wt%。这些结果证实，由于 (HCNS + Pt-NP + Mg - NP) 的 1810 m2 g-1 的非凡 BET 表面积增强和增强了 MgH2 存储能力。
