Abstract: There are several methods to prevent corrosion, such as usage of inhibitors, anodic protection, cathodic protection and coatings. One of the important methods for protection many metals and alloys from corrosion is the use of chemical compounds called corrosion inhibitors. These compounds can be inorganic or organic. Corrosion is prevented either through adsorption or by the formation a protective and insoluble complex film on the surface of metals and alloys. However, these inhibitors are difficult to obtain, expensive, and hazardous compounds. Therefore, the studies of usage of green corrosion inhibitors, generally called eco-friendly corrosion inhibitors are the subject of many researches in recent years. Plant extracts are the most important eco friendly inhibitors. These inhibitors are preferred because of availability, non-toxicity, renewable nature and low cost. Zinc is an important metal used in many industries, such as transportation, energy storage, infrastructure, renewable energy, consumer products and food security etc. However, zinc is an active metal and corrodes in acidic, neutral and alkaline environments. In this review, studies examining the inhibitory properties of plant extracts against corrosion of zinc in different environments are summarized.
