Abstract以气相二氧化硅为硅源,采用溶胶-凝胶法合成了具有高稳定性的LaNi4.25Al0.75/SiO2复合储氢材料。通过高压容积法对该复合材料的储氢特性进行了研究。结果表明,该复合材料具有优良的抗循环粉化性能,并且基本保持了LaNi4.25Al0.75合金的储氢性能。利用该方法可获得表面不同孔径的材料,能满足工程中不同的应用需求。
Other AbstractA LaNi4.25Al0.75/SiO2 hydrogen absorbing composite with high stability was prepared via sol-gel process by mixing water with gas SiO2 and its hydrogen storage performance was examined by a Sieverts-type apparatus. The results indicated that the composite possess excellent pulverization resistance with cycles and almost kept the same hydrogenabsorbing capacity level as LaNi4.25Al0.75 alloy. Different pore sizes on the surface can be attained by this process to meet the requirements of different engineering applications.
