samples show favor hydrogen desorption kinetics. At a temperature as low as 260 °C, all samples could release 75% H2 in 30 min. As expected, the Mg2FeH6 doped with TiMn2 shows the best dehydrogenation... 1 presents the peak temperatures relevant to the DSC consequences. For Mg2FeH6 doped with 5% TiMn2, the dehydrogenation peak temperature is 266.9 °C, nearly 25 °C lower than that of the as-prepared......
the temperature in which equilibrium dissociation pressure of ZrCo alloy attains to 100 kPa. Therefore, a new ZrCo based hydride material that has lower dehydrogenation temperature than 623 K is needed. Adding the third element is considered an effective way to elevate the equilibrium dissociation pressure and/or decrease the dehydrogenation temperature of ZrCo based hydrides, resulting in improving......
investigated. The results show that the doping of a little graphite or graphene lowers the dehydrogenation temperature of MgH2. By contrast, the doping effect of graphene is relatively better and it lowers the initial dehydrogenation temperature of MgH2 by about 33 ℃. Besides, graphite and graphene play the role of structural confinement since they inhibit powder agglomeration during ball-milling......
