摘要

合成的环境友好型四苯基卟啉(TPP)是一种高效的纯Mg抑制剂。TPP可以与mg和形成pp - mg化合物螯合，在mg表面沉淀，这意味着ppp及其衍生物可以作为有效的抑制剂。螯合反应可能是抑制镁腐蚀的一种机制。在此之后，可能会发现更高效的Mg合金缓蚀剂。作者感谢华中科技大学预测与分析中心在分子模拟方面的支持。引用1。E.

A Study on Tetraphenylporphyrin as a Corrosion Inhibitor for Pure Magnesium

Summary Thesynthesizedenvironment-friendlytetraphenylporphyrin(TPP)proved to be an efﬁcient inhibitor for pure Mg. TPP may chelate withMgandformaTPP-Mgcompound,precipitatingonMgsurface.ThismeansthatTPPanditsderivativemayactaseffectiveinhibitorsforMgalloys; chelating reaction could be a mechanism responsible for Mgcorrosion inhibition. Following this, more highly efﬁcient inhibitorsmay be identiﬁed for Mg alloys.
