摘要/Abstract

摘要： 氢气作为清洁燃料在未来的能源版图中将发挥重要作用。电解水制氢反应只生成氢气和氧气，具有成本低、效率高、环境友好、安全性好等优点，而析氧反应是电解水制氢中的一个关键控速反应步骤。介绍了一种简单的Pt负载Li₂Co₂O₄合成方法，并对其析氧性能进行了表征。调控不同的Pt负载量（质量分数），比较对电催化性能的影响，最后得到Pt负载量5%为最优负载量。通过X射线衍射（XRD）、透射电子显微镜（TEM）对材料的结构进行表征，结果表明，得到了一种在保持催化剂的活性与耐久性的同时能够减少Pt消耗的高效催化剂。

关键词: 电解水制氢, Pt负载Li₂Co₂O₄, 高效催化剂

Abstract: Hydrogen as a clean fuel will play a critical role in the future energy landscape. The hydrogen production reaction of electrolytic water only produces hydrogen and oxygen, which has the advantages of low cost, high efficiency, environmental friendliness and good safety. The oxygen evolution reaction is a key ratecontrolled reaction step in hydrogen production from electrolytic water. A simple Pt loaded Li₂Co₂O₄ synthesis method was introduced and its oxygen evolution performance was characterized. The effects of different Pt loading (mass fraction) on the electrocatalytic performance were compared, and the optimum Pt loading was obtained when the Pt loading was 5%. The structure of the material was characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The results show that a highly efficient catalyst capable of reducing the Pt consumption while maintaining the activity and durability of the catalyst is obtained.

Key words: Electrolytic water hydrogen production, Pt loaded Li₂Co₂O₄, Highly efficient catalyst
