1、Temperature dependence of the dissociation pressure ofMgH2,Time line reflecting the development of high-capacity hydrogen storage materials and associated strategies to meet practical targets. Investigations into high-capacity inorganic compounds only took off 20 years ago,following the breakthrough
2、 in reversibility with Ti-doped NaAlH4,Schematic illustration of a) physisorbed, b) chemisorbed, and c) weakly bonded hydrogen,Properties of representative materials for hydrogen distribution, onsite generation and onboardstorage,Table 1 Volumetric and gravimetric Hydrogen content invarious materials,Schematic model of a metal structure with H atoms in the intersticesbetween the metal atoms, and H2 molecules at the surface. Hydrogen atoms are fromphysisorbed hydrogen molecules on the left-hand side and from the dissociation ofwater molecules on the right-hand side.,镁 密排六方晶格,
