Abstract In the present study, comprehensive research efforts were made to experimentally/theoretically examine the corrosion protection capability of Laurus nobilis leaves extract for carbon steel in an acidic medium composed of 1 M HCl. The experimental EIS results evidenced that upon steel exposure to a corrosive electrolyte containing 400 ppm L. nobilis leaves extract the maximum protection performance of 92% was obtained after 2.5 h. The experiments of potentiodynamic polarization proposed a mixed-type anodic/cathodic anti-corrosion action along with small cathodic prevalence. The electronic features established by the DFT approach highlighted that the surface adsorption mechanism could be described by donor-acceptor interactions.

实验补充了月桂提取物作为酸性溶液中碳钢绿色抑制剂的微观（电子/原子）级建模探索

摘要 在本研究中，综合研究工作从实验/理论上检验了月桂叶提取物在由 1 M HCl 组成的酸性介质中对碳钢的腐蚀保护能力。实验 EIS 结果证明，当钢暴露于含有 400 ppm L. nobilis 叶提取物的腐蚀性电解质时，2.5 小时后可获得 92% 的最大保护性能。动电位极化实验提出了混合型阳极/阴极防腐作用，同时阴极发生率很小。DFT 方法建立的电子特征突出表明，表面吸附机制可以通过供体 - 受体相互作用来描述。
