摘要 Titanocene（ CpTiCl3） has been found to be an efficient dopant for the hydrogenation of nanometric magnesium powders. These magnesium powders are generated by the thermal decomposition of magnesium anthracene· 3THF at 90～ 150℃ under vacuum. They can uptake hydrogen to form magnesium hydride even at 185℃ with a hydrogenation rate much higher than those of the undoped ones under normal pressure. The order of the hydrogenation reaction with respect to the nanometric magnesium surface area is one.
