Report Introduction：
Three nano processing techniques employed by the speaker for synthesis of nanostructured Mg-based hydrogen storage materials will be introduced. These techniques are-hydrogen plasma metal reaction, ball milling and catalyzed solution synthesis. By different techniques, Mg-based nanomaterials with different structure and hydrogen storage properties were obtained. Nanosize and catalysis may greatly enhance kinetics of hydrogen absorption and desorption. However, in a size range of 5 to 300 nm, no obvious change in desorption enthalpy and entropy is found. Nevertheless, when catalyzed MgH2 was introduced in the 2LiBH4+MgH2 composite system, for the first time, a change in the reaction pathway was observed. This implies a possibility for design and development of future hydrogen storage systems with tailored thermodynamic values.
Dr. Shao will also share and discuss some interesting points discovered from his research on development of hydrogen storage technologies. For instance, desorption thermodynamics does not change with downsizing and catalysis (first reported in 2004); Dr. Shao reported the lowest absorption temperature in Mg-based hydrogen storage materials in literature (-15oC); From the study on Mg-Co based hydrides with BCC structure metal lattice, he experimentally and computationally verified the semi-empirical rule of minimum hydrogen to hydrogen distance of 2.1 angstrom in interstitial hydrides; Dr. Shao was the first to propose and did some first simulation on a hydrogen-heat coupled Mg/MgH2-SOFC system concept for future stationary energy storage application.
