摘要
在固体聚合物电解池电解水制氢过程中,阳极析氧反应是整个电化学反应的速率控制步骤。本文从固体聚合物电解池析氧催化剂的反应机理、催化剂材料以及制备方法等几个方面进行了详细分析。新的检测手段已经开始应用于原子层级的析氧反应机理研究,对析氧反应活性中间产物有了更深刻的认识;通过优化传统的制备工艺,开发新型的制备方法,进一步提高了析氧催化剂的活性或者稳定性。此外,引入高稳定性、低成本、高活性的催化载体,亦可提高催化剂的性能并相应地降低其成本。希望通过本文的综述总结,为今后阳极析氧催化剂的研究指明方向,推动固体聚合物电解池的商业化进程。
In the process of producing hydrogen by water electrolysis with Solid Polymer Electrolyte（SPE）, anodic oxygen evolution reaction（OER） is the rate-determining step of the whole electrochemical reaction. The progress of the state-of-the-art for the SPE technology in terms of oxygen evolution reaction（OER） mechanism, catalyst materials and its synthesis method are recommended. It is pointed out that new detection methods can analyze OER reaction mechanism and study the intermediate activity products at atomic level. Optimization of the traditional synthesis method and the development of the new method can improve the catalysts performance. In addition, introducing high stability, low cost and high activity carrier material can also improve the performance of catalyst and reduce its cost accordingly. It is hoped that our paper will give a clear direction for the future research of anode catalysts and promote the commercialization of the SPE electrolysis.
