Nano-metal-organic frameworks as corrosion inhibitors for strengthening anti-corrosion behavior of carbon steel in a sulfuric acid environment: from synthesis to applications.

In order to demonstrate the effect of Nano-metal organic frameworks, [Cu(CN)(PhSn) (Pyz2-caH)] (NMOF1) and [[Cu(CN)(MeSn)(Pyz)]] (NMOF2) as corrosion inhibitors for C-steel in 0.5 M sulfuric acid solutions, the following methods were utilized: mass reduction (MR), potentiodynamic polarization (PDP), and AC electrochemical impedance (EIS). The results of the experiments showed that by increasing the dose of these compounds, the inhibition efficacy (%) of C-steel corrosion increased and reached 74.
