The prevailing challenges in H₂ storage and transportation have hindered the widespread utilization of hydrogen as a carbon-neutral energy source. Ammonia is suggested as a promising liquid carrier of hydrogen, from which H₂ can be released by catalytic cracking. In this Short Review, we discuss the recent efforts on the development of NH₃ decomposition catalysts based on Ru, nonprecious metals, bimetallic alloys and high-entropy alloys. The focus of this discussion is on their structure-property relationships and corresponding catalytic mechanisms. After summarizing the previous work, we draw attention to further research directions in the foreground of ammonia as a carbon-neutral liquid fuel.

_{H 2}储存和运输中普遍存在的挑战阻碍了氢作为碳中性能源的广泛利用。氨被认为是一种有前途的氢液体载体，可以通过催化裂化从中释放H _{2 。}在这篇简短的综述中，我们讨论了基于Ru 、非贵金属、双金属合金和高熵合金的_{NH 3分解催化剂}的最新开发进展。本次讨论的重点是它们的结构-性能关系和相应的催化机制。在总结之前的工作后，我们提请关注氨作为碳中性液体燃料的前景的进一步研究方向。
