摘要

In this study, the corrosion inhibition performance of microwave-assisted synthesized α-MoO3 was investigated for steel in a chloride-rich medium containing 0.1 molar potassium chloride solution that was synthesized at various temperatures for assessing the effect of synthesis temperature on its structural and electrochemical behavior. X-ray diffraction analysis confirmed the orthorhombic alpha phase, while FESEM revealed ultrathin nanobelts composed of layered nanosheets. The average crystallite sizes were 68.95 nm for the 180-degree sample and 66.98 nm for the 235-degree sample. Corrosion protection with α-MoO3 was observed in electrochemical impedance spectroscopy and Tafel polarization. Uninhibited steel was most active with the least charge transfer resistance (857 Ω) and the highest double-layer capacitance (3.98 × 10-4 F). The resistance and capacitance of α-MoO3 at 180 °C were at 4436 Ω and 40.8 μF, and at 235 °C were 1563 Ω and 203 μF, respectively. These results confirm the formation of a protective surface film, with maximum inhibition efficiencies of 34 and 28%, indicating mixed-type inhibition. Bode plots and surface analysis revealed denser, smoother, and hydrophobic films. The sample synthesized at 180 °C exhibited higher inhibition efficiency, whereas synthesis at 235 °C produced a more stable and uniform protective film. This is promising for protection against corrosion within chloride and marine environments.
