Herein, the anti-corrosion of carbon steel in 1 M HCl by two newly synthesized pyrazolotriazole derivatives, namely, 6-methyl-1H-pyrazolo[5,1-c][1,2,4]triazole-7-carbonitrile (CPT) and 1-acetyl-6-methyl-1H-pyrazolo[5,1-c][1,2,4]triazole-7-carbothioamide (MPT), was studied using electrochemical, density functional theory (DFT), and molecular dynamics (MD) simulation techniques. The experimental results
在此,通过两种新合成的吡唑并三唑衍生物,即6-甲基-1 H-吡唑并[5,1- c ][1,2,4]三唑-7-腈( CPT) 和 1-acetyl-6-methyl-1 H - pyrazolo[5,1- c][1,2,4]triazole-7-carbothioamide (MPT),使用电化学、密度泛函理论 (DFT) 和分子动力学 (MD) 模拟技术进行了研究。实验结果表明,抑制剂的浓度对其抑制效率有显着影响。动电位极化曲线表明这两种吡唑并三唑是混合型抑制剂。采用DFT计算探索分子活性,并进行MD模拟以获得抑制剂分子与铁表面之间的相互作用能。使用理论计算技术获得的结果与通过实验获得的结果一致。
