在900 ℃的石英管中，通过蒸发金属锌的方法快速合成了平均直径为20 nm的块状ZnO纳米线。不需要金属催化剂、石墨添加剂和真空，更重要的是，对于大规模工业化来说非常方便和有效。在室温下研究了ZnO纳米线的储氢特性。在约3.03 Mpa的压力下达到0.83 wt%的最高储存容量，并且在室温下的环境压力下可以释放约71%的储存的氢气。(C)2004年，美国物理学会。
Massive ZnO nanowires with the mean diameter of 20 nm have been rapid synthesized by evaporation of metal zinc at 900degreesC in the quartz tube. Metal catalyst, graphite additive, and vacuum are not necessary, and, more importantly, it is very convenient and effective for large-scale industrialization. The hydrogen storage characteristics of the synthesized ZnO nanowires are investigated at room temperature. The highest storage capacity of 0.83 wt% is achieved under the pressure of about 3.03 Mpa, and about 71% of the stored hydrogen can be released under ambient pressure at room temperature.
