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
