Chemical, electrochemical and surface studies of new metal-organic frameworks (MOF) as corrosion inhibitors for carbon steel in sulfuric acid environment.

ABSTRACT: The effects of [Co₂ (SCN) 4(hmt)₂(H₂O)₆. H₂O] (SC1) and [Co (CN)₆ (Me₃Sn)₃(H₂O). (qox)] (SCP2) MOF as corrosion inhibitors on C-steel in 0.5 M sulfuric acid solutions are illustrated utilizing mass reduction (MR), electrochemical [potentiodynamic polarization (PP), and AC electrochemical impedance (EIS)]. The experiments revealed that as the dose of these compounds rose, the inhibition efficacy (IE percent) of C-steel corrosion improved, reaching 80.7-93.1% at dose 25 × 10^-6 M for SC1 and SCP2, respectively. IE percent, on the other hand, dropped as the temperature range grew. SC1was adsorbed physically and chemically (mixed adsorption) but SCP2 was adsorbed physically on the surfa
