Newly synthesized salicylidene-4,4′-dimorpholine (SDM) assembled on nickel oxide nanoparticles (NiONPs) and its inhibitive effect on mild steel in 2 N hydrochloric acid

- Nanoparticles with inhibitor were found to be better corrosion inhibitor than only organic compound.
- A strong binding mechanism was confirmed by FTIR, PXRD.
- Inhibition efficiency increases drastically for SDM assembled on NiONPs as compared to SDM.
- The adsorption model obeys Langmuir adsorption isotherm.
- The protective layer over the surface of mild steel has been confirmed by AFM analysis.
