ecological or green inhibitors, to replace the toxic organic inhibitors actually used in the industry that could be plant extract, drugs, amino acids.....
I think that there is less-enough availability information in the literature for the application of these green inhibitors in the industrial application, and also about the inhibition mechanisms of these compounds onto the metal surface.
Most of these eco-friendly inhibitors were examined in the laboratory conditions before the step of the application. The near future maybe will give the best answer!!!
