【摘要】 本文报道了常温高压下天然矿物坡缕缟石在不同处理条件下的吸氢行为。实验结果表明,经盐酸处理,保型升华干燥并在280℃加热后的坡缕缟石吸氢性能最大,其饱和吸氢量达0.63Wt％,与纳米碳管的吸氢量具有一定的可比性。更多还原

【Abstract】 The hydrogen adsorption of palygorskites-one kind of mines with their structures and sizes similar to those of carbon nanotubes, in their different pretreated conditions. The results showed that palygorskite treated with hydrochloric acid, finozen and then sublimed at low pressure has the largest hydrogen adsorption capacity. The amount of hydrogen adsorbed by one gram of purified palygorstite is 0.63 weight percent, comparable to the weight of hydrogen absorbed by per gram of carbon nanotubes.更多还原
