Over the past century, a substantial amount of research focused on developing corrosion inhibitors, with a special focus on green "plant-based" corrosion inhibitors. Among the various types of inhibitors, polyphenols emerged as a promising candidate due to their advantageous characteristics, which include being inexpensive, biodegradable, renewable, and, most importantly, safe for both the environment and humans. Their performance as sustainable corrosion inhibitors have encouraged many electrochemical experiments as well as theoretical, mechanistic, and computational studies, with many papers reporting inhibition efficiencies of over 85%. In this review, the majority of literature contributions on the inhibition of various types of polyphenols, their natural extraction techniques, and their applications as "greener" corrosion inhibitors for metals are thoroughly described and discussed with a focus on their preparation, inhibition mechanism, and performance. Based on the reviewed literature, it can be concluded that polyphenols have a very promising potential to be used as both green and powerful corrosion inhibitors; therefore, further investigations, experimental or computational, are still required to realize higher inhibition efficiencies reaching up to ≈ 100%.
在过去的一个世纪里，大量研究聚焦于开发缓蚀剂，特别关注绿色的“植物基”缓蚀剂。在各类缓蚀剂中，多酚因其具有价格低廉、可生物降解、可再生且最重要的是对环境和人类安全等优势特性，成为了一个有前景的候选者。它们作为可持续缓蚀剂的性能促使了许多电化学实验以及理论、机理和计算研究的开展，许多论文报道的缓蚀效率超过了85%。在这篇综述中，对关于各类多酚的缓蚀作用、其天然提取技术以及它们作为金属“更绿色”缓蚀剂的应用等方面的大部分文献贡献进行了全面描述和讨论，重点关注其制备、缓蚀机理和性能。基于所综述的文献，可以得出结论：多酚作为绿色且高效的缓蚀剂具有非常有前景的潜力；因此，仍需要进一步的实验或计算研究来实现高达≈100% 的更高缓蚀效率。
