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。
Chemical hydrogen storage materials require high hydrogen storage capacity. Ammonia borane (NH3BH3, AB) hydrogen content of up to 19.6 wt%, is a potential application of hydrogen storage media. AB has a hydrogen-releasing capacity of up to 7.8 wt% and thermally released hydrogen can release 19.6 wt% of hydrogen, demonstrating its great potential for chemical hydrogen storage. In the AB hydrogen study, the catalyst is the core technology and an important direction. Due to the excellent catalytic performance of nanocatalysts in the hydrogen abstraction of AB, this paper will summarize and prospect the research on the performance of ammonia-borohydride nanosized metal catalysts.
