Abstract
Titanium nanocomposite (TiTR) was synthesised from Triumfetta rhomboidea leaf extract and used as corrosion protection of mild steel (MS) in 1 M hydrochloric acid. The corrosion inhibition process of the nanocomposite was explored using weight loss, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarisation (PDP). The corrosion inhibition performance of TiTR is a function of concentration and temperature. The results revealed that TiTR was 84.27% efficient in limiting MS corrosion at 1.0 g L−1 and 3 h. The TiTR acted as a mixed-type corrosion inhibitor and Langmuir isotherm indicated that TiTR was adsorbed on mild steel through physisorption by forming a monolayer of film. Surface morphology study of MS visually confirmed the protection of MS by TiTR through film formation.
