摘要：

We review hydrogen-storage properties of two nano-structured systems; multi-layered Pd/Mg films prepared by the RF sputtering method and mechanically milled graphite under a high hydrogen atmosphere. The former prepared under optimized RF sputtering conditions absorbs hydrogen of similar to5 mass% at 373 K under 0.1 MPa hydrogen pressure, and desorbs all the hydrogen at 360 K in vacuum. The latter prepared by milling for 80 h absorbs hydrogen up to 7.4 mass%. Hydrogen molecules are desorbed by the two processes above at 600 and 950 K, respectively. (C) 2002 Elsevier Science B.V.
