考察了纳米LiH在不同温度热处理后比表面积的变化及其与Cp2TiCl2组成催化剂的加氢反应活性之间的关系．300℃热处理后LiH比表面积已呈较大幅度的下降，但催化剂的加氢反应活性反而更高，说明比表面积是构成纳米LiH高活性的一个主要原因，但不是唯一的因素．

The effects of heat treatment at different temperatures under Ar atmosphere on the specificsurface area and particle size of nanometric lithium hydride as well as its catalytic activity inhydrogenation have been studied. The specific surface area of LiH treated at 300 ℃ decreasessignificantly, whereas a much higher catalytic activity is achieved with catalyst composed ofnanometric LiH and Cp2TiCl2. This result indicates that the large specific surface area of nanometricLiH is a major factor but not the only factor for its high activity.
