Performance of green corrosion inhibitors from biomass in acidic media

There has been a strong interest worldwide in developing suitable technologies that can derive chemicals and materials from renewable biomass in a number of applications, including corrosion inhibitors. In spite of the efficacy of conventional inhibitors in corrosion control, current corrosion inhibitors exhibit toxicity and/or are non-biodegradable. Therefore, industry efforts are leading to the development of non-toxic and environmentally friendly "green" corrosion inhibitors from renewable resources. Extensive studies of different bio-based inhibitors show that a vast number of phytochemicals can be used as efficient corrosion inhibitors. This paper provides a comprehensive review of the corrosion inhibition properties of plant-derived chemicals classified under the parameters provided by botanical chemistry.
