This review summarizes advances, opportunities, and recent progress in green and sustainable corrosion inhibitors for non-ferrous metals and alloys in different corrosive environments. These corrosion inhibitors usually consist of plant extracts usually comprises of organic compounds encompassing heterocyclic, multiple bonds, and various other functional groups. Due to the existence of multiple functional groups and heteroatoms, organic compounds adsorption becomes favorable on the surface of the metal, which efficiently reduces the deterioration of metals. In this review article, literature based on corrosion inhibition of non-ferrous metal/alloys by green inhibitors has been assessed, and the significant findings and performance of these inhibitors for aluminium/ NaOH and copper/ HNO₃ have been emphasized. The application and role of density functional theory has also been discussed in the prediction of Inhibition efficiency of major constituents green inhibitors. In addition, the possible mechanism of corrosion inhibition from literature is also summarized to understand the role of green inhibitors. The non-toxic nature of the phytochemicals makes them suitable candidates as green and sustainable corrosion inhibitors.

这篇综述总结了在不同腐蚀环境下有色金属和合金的绿色和可持续腐蚀抑制剂的进展，机遇和最新进展。这些腐蚀抑制剂通常由植物提取物组成，植物提取物通常由有机化合物组成，所述有机化合物包含杂环，多个键和各种其他官能团。由于存在多个官能团和杂原子，有机化合物在金属表面的吸附变得有利，从而有效地减少了金属的劣化。在这篇综述文章中，评估了基于绿色抑制剂对有色金属/合金的腐蚀抑制作用的文献，并且这些抑制剂对铝/ NaOH和铜/ HNO ₃的重要发现和性能已经强调。还讨论了密度泛函理论在预测主要成分绿色抑制剂抑制效率中的应用和作用。另外，还总结了文献中抑制腐蚀的可能机理，以了解绿色抑制剂的作用。植物化学物质的无毒性质使其适合作为绿色和可持续的腐蚀抑制剂。
