Hydrogenation properties and kinetic study of MgH_2 - x wt% AC nanocomposites prepared by ball milling
Environmental Science and Pollution Research, 2020Co-Authors: Kanhaiya Chawla, Deepak Kumar Yadav, Abhinav Bajpai, Sushant KumarAbstract:The high de-/hydrogenation temperature of magnesium hydride is still a challenge in solid-state hydrogen storage system for automobiles applications. To improve the hydrogenation properties of MgH_2, we select activated carbon/charcoal (AC) as a catalyst. A systematic investigation was performed on the hydrogen storage behaviors of MgH_2 and MgH_2 - 5 wt% AC nanocomposites, which were prepared by a high-energy planetary ball mill. These synthesized nanocomposites were characterized by X-ray diffraction (XRD), high-resolution transmission electron microscope (HRTEM) for phase identification, surface morphology and microstructural analysis. The pressure-composition-temperature (PCT) isotherm investigation shows the maximum hydrogen storage capacity ~ 6.312 wt% for MgH_2-AC nanocomposites, while 3.417 wt% for MgH_2 at 300 °C. The onset temperature for MgH_2-AC nanocomposites is shifted towards lower side than the 50 h milled MgH_2. The HRTEM study show the activated carbon helps to Reduce Oxygen from MgO phase in MgH_2, so that significantly improvement achieved in the absorption capacity and kinetics also for the MgH_2-AC nanocomposites. The presence of β - and γ -phases of MgH_2 in MgH_2-AC nanocomposites also supports the high hydrogenation properties and with the support of XRD data.
