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