Experimental and quantum investigations of novel corrosion inhibitors based triazene derivatives for mild steel

Abstract

• Triazene derivatives were used as novel corrosion inhibitors. • Different electrochemical techniques were used to study the inhibition behavior. • Triazene compounds showed a high inhibition activity of 98.51%. • Quantum chemical calculations supported the electrochemical findings. The present work investigates some triazene compound's anti-corrosion properties as novel corrosive inhibitors by experimental and theoretical studies. Different electrochemical and morphological techniques were used to study the compound's corrosion inhibition. The experiments were performed in 1 M H 2 SO 4 at different inhibitor concentrations and temperatures. The results showed that triazene compounds are effective inhibitors for mild steel corrosion in an acidic medium. Gaussian 09W software was used to calculate the compound's quantum chemical data, and there was an excellent approval between the experimental and quantum chemical calculations.
