摘要

在本研究中，我们开发了具有增强π-π相互作用的离子液体修饰的氮掺杂碳点（IL-NCDs），有效地解决了传统碳点在强酸性条件下的聚集问题。合成的IL-NCDs在1 M HCl溶液中表现出优异的分散性和长效保护性能，在60 mg/L浓度下，缓蚀效率为97.34 %，保护时间超过20天。优化的表面电荷和增加的活性位点有助于形成致密的保护膜，为酸性环境下的金属腐蚀保护提供了一种高效环保的解决方案，具有巨大的工业应用潜力。

Regulating π-π interactions in carbon dots via N-doping & ionic liquid modification for enhanced efficiency in 1 M HCl

In this study, we developed ionic liquid-modified nitrogen-doped carbon dots (IL-NCDs) with enhanced π-π interactions, effectively addressing the aggregation issue of conventional carbon dots in strong acidic conditions. The synthesized IL-NCDs demonstrated superior dispersibility and long-term protective performance in 1 M HCl, achieving a corrosion inhibition efficiency of 97.34 % at 60 mg/L and maintaining protection for over 20 days. The optimized surface charge and increased active sites facilitated the formation of a dense protective film, offering an efficient and eco-friendly solution for metal corrosion protection in acidic environments, with significant potential for industrial applications.
