Abstract: The catalyst for the ammonia decomposition to produce hydrogen is particularly important. The composition,structure,substrate,auxiliary agent and so on,all can affect the activity of catalysts. The researches of catalyst modification in recent years was systematically reviewed based on the change of the morphologies and microstructure of catalysts,the influence of different substrate,the doping and modification of promotes. Meanwhile,the application of ore and industrial waste in ammonia decomposition were introduced. It is pointed out that the synergic effect between hosts and carrier/additives promotes the selectivity of hydrogen production,which possesses great potential and practical value for further design of new catalyst employed at low pressure and low temperature for ammonia decomposition. Reducing the energy consumption of the ammonia decomposition should be the research direction of the catalysts in the future.

Key words: hydrogen production, catalyst support, catalyst activation, synergistic effect

摘要: 在氨分解制氢技术中催化剂的选取尤为重要,其组成、形貌结构、载体、助剂等均能影响催化剂活性发挥。本文综述了近几年国内外氨分解制氢催化剂的改性研究现状,对催化剂的形貌结构变化、不同载体的影响、助剂的添加、矿石及工业废品在氨分解中的应用进行了详细的介绍,指出有效发挥催化剂和载体、助剂等之间的协同作用,改善外部条件,对于实现氨分解制氢具有很好的潜在实用价值,进一步设计出低压、低温、高活性氨分解的新型催化剂,降低能量消耗是未来氨分解催化剂的研究方向。
