Owing to the increasing ecological awareness, development and consumption of the environmental friendly ma- terials are highly essential in every field of science and technology. One of such materials is ionic liquids. Ionic liq- uids are associated with several advantageous properties including low melting point, low vapor pressure, low toxicity, high polarity and extremely high stability to thermal and chemical treatments. Because of their high sol- ubility and excellent anticorrosion activity, ionic liquids are widely employed as corrosion inhibitors for metals and alloys in different electrolytic media. Presence review article features the collection of major recent (mainly 2015–2020) advancement on ionic liquids as corrosion inhibitors. This article gives a brief outline about the prop- erty and application of ionic liquids. Basic information about corrosion, it adverse effect and mechanism of corro- sion inhibition have also be described.
