摘要
论述了金属合金和碳材料的储氢机理、吸放氢量和动力学性能;探讨了活性金属Ni、Pd、Li和K对碳材料储氢的催化性能和金属Mg与多壁纳米碳管、碳纳米纤维、高比表面积活性炭、无烟煤和纳米石墨等碳材料复合储氢的性能及机理;指出了储氢材料应该向Li、Na、Mg、Al、B等轻元素和无烟煤、石墨等储量大、赋存广、成本低的碳材料方向发展。
Hydrogen-storage mechanism, absorbing and disrobing hydrogen capacity and kinetics of metal alloys and carbon materials are summarized. The catalytic performance of active metal（Ni, Pd, Li and K）on bydrogen storage of carbon material and hydrogen-storage performance and mechanism of Mg composed with carbon materials, including multi-walled carbon nanotubes, carbon nanofibres, active carbon, anthracite and graphite, are discussed. Anthracite and graphite which are high deposited, broadly existing and low price, and light elements （Li, Na, Mg, Al, B and so on） ,are deemed to be used as hydrogen storage materials, and the developmental direction is pointed out.
