摘要

封面展示了不同碱金属阳离子如何影响金表面的阴极腐蚀。在高负电位下极化金会产生各种结构：使用 CsOH 会产生纳米多孔表面，使用 KOH 会产生球形纳米颗粒和三角形凹坑，使用 NaOH 会产生八面体纳米晶体，使用 LiOH 会产生三角形凹坑。本研究还强调了电解液纯度的关键作用，因为 CsOH 中的微量铁和镍杂质会对阴极腐蚀产生重大影响。更多信息，请参阅 Mohamed M. Elnagar、Ludwig A. Kibler 和 Timo Jacob 的研究文章（DOI: 10.1002/cctc.202400526）。

Front Cover: Effect of Alkali Metal Cations and Trace Metal Impurities on Cathodic Corrosion of Gold Electrode Surfaces (ChemCatChem 18/2024)

The Front Cover illustrates how different alkali metal cations influence the cathodic corrosion of gold surfaces. Polarizing gold at highly negative potentials results in various structures: nanoporous surfaces with CsOH, spherical nanoparticles and triangular pits with KOH, octahedral nanocrystals with NaOH, and triangular pits with LiOH. The study presented here also highlights the crucial role of electrolyte purity, as trace iron and nickel impurities in CsOH significantly impact cathodic corrosion. More information can be found in the Research Article by Mohamed M. Elnagar, Ludwig A. Kibler, and Timo Jacob (DOI: 10.1002/cctc.202400526).
