摘要

近年来，碳壳作为可应用于氧进化反应（OER）电催化剂以防止其在碱性条件下腐蚀的保护层而备受关注。然而，热力学考虑和实验结果表明，这些碳壳本身也会受到腐蚀，从而限制了它们作为抗氧化保护层的适用性。本文通过光谱学、能谱学、晶体学、显微学和电化学测量，介绍了碳腐蚀的热力学，强调了碳在碱性 OER 条件下不可避免的降解。然后，讨论了抑制碳腐蚀的最新研究成果，以及水氧化研究中碳壳的未来发展方向。

A Perspective on Protective Carbon Shells for Improved Stability of Alkaline Water Oxidation Electrocatalysts

In recent years, carbon shells have garnered attention as possible protective layers that can be applied to oxygen evolution reaction (OER) electrocatalysts to prevent corrosion under alkaline conditions. However, thermodynamic considerations and experimental results indicate that these carbon shells are subject to corrosion themselves, limiting their applicability as protective coatings against oxidation. Herein, the thermodynamics of carbon corrosion are presented with spectrometric, spectroscopic, crystallographic, microscopy, and electrochemical measurements, emphasizing the inevitable degradation of carbon under alkaline OER conditions. Recent work focused on suppressing this carbon corrosion is then discussed alongside future directions for carbon shells in water oxidation research.
