Abstract Influence of novel green Elaeis guineensis (EG) and silver nanoparticles (AgNPs) on the improved corrosion resistance of mild steel against acute acid attack is reported. Such EG/AgNPs were synthesized from palm oil leaf extracts and used as inhibitor with varying contents to inspect the feasibility of modifying the acid (1 M HCl(aq)) mediated anti-corrosion behaviour of mild steel. The structural and morphological properties of the extracted EG/AgNPs inhibitor (in powder form) were determined using TEM, XRD, and EDX analyses. Furthermore, the acid solution exposed mild steel specimens were characterized via FESEM, EDX, AFM, XRD, weight loss, polarization and electrochemical impedance measurements. Mild steel surface was found to adsorb the EG/AgNPs and formed a protective film advantageous for inhibiting the acid attack. Steel specimen incorporated with 10% (v/v) of EG/AgNPs inhibitor revealed maximum inhibition efficiency of 94.1%.

提高低碳钢对酸活化的耐腐蚀性：新型 Elaeis guineensis 和银纳米颗粒的影响

摘要 报道了新型绿色 Elaeis guineensis (EG) 和银纳米粒子 (AgNPs) 对改善低碳钢对急性酸侵蚀的耐腐蚀性的影响。这种 EG/AgNPs 是由棕榈油叶提取物合成的，并用作具有不同含量的抑制剂，以检查改变酸（1 M HCl（aq））介导的低碳钢抗腐蚀行为的可行性。使用 TEM、XRD 和 EDX 分析确定提取的 EG/AgNPs 抑制剂（粉末形式）的结构和形态特性。此外，通过 FESEM、EDX、AFM、XRD、重量损失、极化和电化学阻抗测量对酸溶液暴露的低碳钢试样进行了表征。发现低碳钢表面吸附 EG/AgNPs 并形成有利于抑制酸侵蚀的保护膜。
