High-temperature ammonia decomposition is a promising method for hydrogen production, but high temperatures and low conversion rates limit its wide application. In order to solve this problem, the development of nano-materials is essential to achieve high performance ammonia oxidation decomposition. In this paper, ordered mesoporous Co/CeO2 catalyst was synthesized by codeposition method and a new process of ammonia hydrogen production was developed and designed without the need for external heating. The catalyst was characterized by XRD, BET and TEM. The results show that the catalyst activity is the highest when Co content is 10wt%. When the molar ratio of NH3/O2 is 4:1, the bed temperature increases from 165°C to 405°C, the conversion rate of NH3 and O2 is 72% and 81%, respectively, and the productivity of H2 is 45%. The catalyst also showed good stability and reusability.
