摘要:

乙醇制氢具有环保、清洁、可持续等优点,其关键在于选择合适的催化剂。相较于贵金属催化剂而言,Ni与Co基催化剂因其具有成本低且活性高的优点,近年来在乙醇催化制氢中逐渐成为研究热点。然而Ni与Co基催化剂在催化乙醇水蒸气重整制氢的过程中仍存在着稳定性较差、低温催化活性低和使用寿命较短等问题。本文介绍了乙醇制氢的机理,围绕载体的类型及催化剂活性纳米颗粒的合金化改性,综述了近年来Ni与Co基催化剂催化乙醇水蒸气重整制氢的研究现状,总结了提高催化剂性能的方法及措施,并展望了Ni与Co基催化剂未来的发展方向,为颗粒尺寸小且低温催化活性高、稳定性好的Ni与Co基催化剂的制备提供思路。

Abstract:

Hydrogen production from ethanol has the advantages of environmental friendliness, cleanliness, and sustainability. The key to this technology is the appropriate catalyst. Compared with noble metal catalysts, the Ni-based and Co-based catalysts have advantages of low cost and high activity and have become a research hotspot in recent years. However, there are still some problems in the process of ethanol steam reforming with the Ni-based and Co-based catalysts, such as poor stability, low catalytic activity at low temperature and short life time. Therefore, this paper firstly introduces the mechanism of hydrogen production from ethanol. Based on the types of support and the alloying modification of active catalyst nanoparticles, we then reviews the recent research results of Ni-based and Co-based catalysts for hydrogen production from ethanol steam reforming. Thereafter the methods to improve the performance of the catalysts are summarized. Finally, the future development direction of Ni-based and Co-based catalysts is prospected, which provides ideas for the preparation of Ni-based and Co-based catalysts with small particle size, high low-temperature catalytic activity and good stability.
