“…The peaks at 3373, 1638, and 1585 cm –1 observed in the spectrum of o -phenylenediamine correspond to stretching of NH 2 , CC, and aromatic ring. , The peak at 749 cm –1 is related to out-of-plane bending vibration of aromatic CH . In the spectrum of thiourea, 1608 and 3375 cm –1 peaks agree to shearing and stretching vibrations of NH 2 while the one at 1477 cm –1 agrees to CS stretching . The peaks observed for CDs are the typical peaks of the CN stretching vibration of NH/OH that appeared at 3113 and 1410 cm –1 .…”

N and S codoped carbon dots having good water solubility have been successfully made by a novel hydrothermal method and characterized by FTIR, XPS, and TEM. The as-synthesized CDs were carbon particles rich in polar functional groups less than 10 nm in size. Electrochemical measurements, gravimetry, and surface analysis methods were utilized to examine the inhibition characteristics and adsorption mechanism of CDs on the carbon steel in acid pickling solutions. Electrochemical measurements verified that the CDs displayed adequate protection with high inhibition efficiency of 97.8%. The long-term weightloss experiments up to 72 h further confirmed the excellent corrosion inhibition at room temperature and 313 K. The results presented are helpful for the formulation of more effective acid pickling corrosion inhibitors.

“…It was observed that the plant mass, which contains a high amount of polyphenols (flowers and leaves), shows better antioxidant activity and better inhibition efficiency. (Mechbal et al 2021 ). Raphanus sativus L. was also found as an effective inhibitor and antiscalant for mild steel, even in tap water.…”

An eco-friendly approach to inhibit the corrosion of boiler quality (BQ) steel by onion waste in acidic media was investigated. The extract from onion peel was characterized using the conventional extraction method and was characterized using HPLC. The efficacy of the onion peel extract (OPE) as a green corrosion inhibitor was studied using the weight loss method and a variety of electrochemical techniques, including open-circuit potential (OCP), potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS). The Tafel polarization revealed that at 200 mg L −1 of onion peel extract (OPE), corrosion current density was reduced maximum in both 1 (M) HCl and 0.5 (M) H 2 SO 4 media. From the electrochemical impedance spectroscopy studies, the maximum inhibition efficiencies of 91.30% and 90.71% were found at 200 mg L −1 in 1 (M) HCl and 0.5 (M) H 2 SO 4 , respectively. The Langmuir isotherm was determined to be the best-fitting model, and the thermodynamic parameter, such as free energy , was computed, which indicated the physisorption of OPE onto the BQ surface. In theoretical investigations, density functional theory DFT was used to determine the adsorption efficiency and reactive sites of the OPE molecule by exploring various quantum chemical parameters.
