摘要:

质子交换膜(PEM)水电解的阳极催化剂需要耐受强酸性环境以及析氧反应(OER)条件下的高氧化电位。为了加深对酸性介质中OER过程的理解以开发具有更好稳定性与更高活性的电催化剂,研究和发展原位表征技术显得尤为重要。该综述介绍了几种用于酸性OER研究的原位表征技术,包括:原位X射线光电子能谱技术、原位X射线吸收谱技术、原位X射线衍射/散射技术、原位电化学红外技术、原位电化学拉曼技术、原位电感耦合等离子体-质谱技术、微分电化学质谱/在线电化学质谱技术、电化学石英微晶天平技术。重点讨论了这些技术的原位装置设计以及它们在酸性OER研究领域的具体应用。最后总结了这些技术的特征,并指出用于酸性OER的原位表征技术的发展之有待解决的问题,即新技术的研发与原位技术间的联用、原位装置的改进及时空分辨率的提高。

Abstract:

The anode catalysts used in proton exchange membrane (PEM) water electrolysis must be resistant to the harsh oxidation environment that occurs during the oxygen evolution reaction (OER). The investigation and application of in-situ/operando characterization techniques are critical for developing acidic OER catalysts with high stability and activity. Herein, several in-situ/operando characterization techniques for acidic OER research are introduced, including in-situ/operando X-ray photoelectron spectroscopy, in-situ/operando X-ray absorption spectroscopy, in-situ/operando X-ray diffraction/scattering, in-situ/operando electrochemical infrared spectroscopy, in-situ/operando electrochemical Raman spectroscopy, in-situ/operando inductively coupled plasma mass spectrometry, differential electrochemical mass spectrometry/on-line electrochemical mass spectrometry, in-situ/operando electro-chemical infrared spectroscopy, in-situ/operando electrochemical Raman spectroscopy, in-situ/operando inductively coupled plasma mass spectrometry, differential electrochemical mass spectrometry/on-line electrochemical mass spectrometry, electrochemical quartz crystal microbalance. Special attention is paid to the device structure and application value of these in-situ/operando characterization techniques for OER in acidic media. Finally, the characteristics of these techniques are summarized, and the challenges for the development of in-situ characterization techniques, such as the development of new techniques and the combination of in-situ techniques, the improvement of in-situ devices, and space-time resolution, are highlighted.

Key words: proton exchange membrane, water electrolysis, oxygen evolution reaction, in-situ/operando characterization techniques
