In situ highly sensitive potential- and time-resolved monitoring of polycrystalline gold and platinum electrochemical dissolution in pure organic media is reported. This was achieved by successfully upgrading electrochemical flow cell coupled to inductively coupled plasma mass spectrometry. Similar to the aqueous media, aggressive transient dissolution takes place during oxide formation and reduction. In contrary to the aqueous electrolyte, both gold and platinum exhibit enhanced anodic compared to the cathodic oxide-assisted dissolution in organic media. This study intends to highlight the capabilities of the new methodology, which will expand the studies of metals dissolution to the fields like organic electrocatalysis, corrosion, battery research, and sensors among others.

据报道，在纯有机介质中对多晶金和铂电化学溶解的原位高度敏感的电势和时间分辨监测。这是通过成功升级与电感耦合等离子体质谱联用的电化学流通池而实现的。与水性介质相似，在氧化物的形成和还原过程中会发生剧烈的瞬态溶解。与水性电解质相反，与在有机介质中的阴极氧化物辅助溶解相比，金和铂均表现出增强的阳极性能。这项研究旨在强调新方法的功能，它将把金属溶解的研究扩展到有机电催化，腐蚀，电池研究和传感器等领域。
