Magnesium hydride (MgH2) is one of the most promising hydrogen storage materials for practical application due to its favorable reversibility, low cost and environmental benign; however, it suffers from high dehydrogenation temperature and slow...
A hydrogen storage alloy having an atomically engineered microstructure that both physically and chemically absorbs hydrogen. The atomically engineered microstructure has a predominant volume of a first microstructure which provides for chemically absorbed hydrogen and a volume of a second microstructure which...
Mg@C纳米复合材料的吸/放氢焓显著降低至-62.0/63.1 kJ mol-1H2,在200℃下可吸附4.4 wt% H2,250℃下可释放4.0 wt% H2,吸/放氢活化能降至惊人的53.1/74.2 kJ mol-1H2。该研究工作以“MgBu2nanosheets encapsulated in ZIF-8 ...
Over the last decade's magnesium and magnesium based compounds have been intensively investigated as potential hydrogen storage as well as thermal energy storage materials due to their abundance and availability as well as their extraordinary high gravimetric and volumetric storage densities. This review ...
The notable improvement of hydrogen storage properties of MgH2 is attributed to the reversible phase transitions of Mg2Co/Mg2CoH5 and Mg2Ni/Mg2NiH4, and the excellent thermal conductivity and confinement effect of the carbon shell. As a result, the apparent activation energy of dehydrogenation ...
In this paper, the nanocrystalling composite Mg-Ni-TiO2-CNTs was made by mechanical ball milling under hydrogen pressure of 5.0u00d710-5Pa, The hydrogen storage properties and operation temperatures were investigated. It was found that the composite can absorb 7.5wt.% hydrogen in 60s under 5.0...
