| 英文摘要 | Hydrogen generation material is a new kind of energy material that can supply hydrogen by reacting with water and is drawing more and more attention with the development of hydrogen economy. In this study, a novel nanoporous magnesium-lithium material prepared by a physical vapor deposition method exhibits an excellent hydrogen generation property. It generates hydrogen efficiently and quickly with saltwater, reaching a hydrogen generation amount of 962 mL g -1 and hydrogen generation rates of 60 mL g -1 min -1 , 109 mL g -1 min -1 , 256 mL g -1 min -1 and 367 mL g -1 min -1 at 0 degrees C, 25 degrees C, 35 degrees C and 50 degrees C, respectively. The nanoporous magnesium-lithium material is composed of a solid solution phase with a magnesium-lithium atomic ratio of 17:3. By synchrotron radiation analysis, the sizes of the nanopores are in the range of 100 nm similar to 600 nm with an average size of 280 nm, and the porosity is calculated to be similar to 42.4%. The improved hydrogen generation property is attributed to the nanoporous structure with a high specific surface area, and the addition of lithium element which acts as active sites in hydrogen generation process.
