化学储氢材料要求具有高的氢存储容量。氨硼烷(NH3BH3,AB)的氢含量高达19.6 wt%,是一种具有潜在应用前景的氢存储介质。AB的水解释氢容量高达7.8 wt%,热解释氢则可释放出19.6 wt%的氢,显示出其在化学储氢方面的巨大潜力。在AB释氢研究中,催化剂是研究的核心技术和重要方向。由于纳米催化剂在AB释氢中所表现出的优良催化性能,本文将对氨硼烷释氢纳米金属催化剂及其性能的研究进行全面的总结和展望。
As the chemical hydrogen storage material,it must have a high hydrogen storage capacity. Ammonia borane( NH3BH3,AB),whose hydrogen content is as high as 19. 6 wt%,is regarded as a potential hydrogen storage medium w ith the bright future. The capacity of AB hydrolysis dehydrogenation is up to 7. 8 w t%. The capacity of AB pyrolysis dehydrogenation can release 19. 6 w t% of hydrogen. Both the hydrolysis dehydrogenation and the pyrolysis dehydrogenation have show n its great potential in the chemical hydrogen storage. In the study of AB dehydrogenation,catalyst is the key technology and the important research direction. Among all the catalysts about AB dehydrogenation,nano metal catalysts have been investigated for their excellent performance. In this paper,the nano catalysts and their performance about the dehydrogenation of ammonia borane are review ed.
