摘要：Mixed-valence compounds are important materials in the field of chemistry and physics due to their excellent physicochemical properties and magnetoelectric effects. Under the protection of nitrogen, the mixed-valence (MnxMn0.05-x2+Zn0.95O)-Mn-0 dilute magnetic solid solutions (5MZO DMSs) are prepared, simultaneously inhibiting both anode and cathode electrochemical corrosion. The penetration and transfer of oxygen are slowed down due to the abundant crystal defects in SMZO-5 DMS, causing anoxia in the cathode. In addition, plenty of photoelectrons generated by SMZO-5 DMS inhibit the reaction of iron electron loss, and the path of charge transfer is prolonged due to the excellent magnetic property of SMZO-5 DMS. Thus, the anticorrosion performance of SMZO-5 DMS is enhanced to 206.5% compared to that of the ZnO material after 72 h. In particular, the SMZO-5 DMS is resistant to the rapid corrosion attenuation at high temperatures, meeting the need of anticorrosion under the harsh environment.
