“…The decrease of both Tafel anode and cathode slopes of Cu-HAP (Table ) indicates that the spin polarization of Cu-HAP effectively promotes the electron transfer. In addition, the weak magnetism of the sample induces a deflection of the path of motion of the anodically generated electrons . The electron transfer to the cathode slows down or decreases, leading to the inhibition of the whole corrosion electrochemical process.…”

Hydroxyapatite (HAP) with point defects was designed under simple liquid-phase conditions. The presence of V O , O − radical vacancies, and −OH radicals achieved the capture of oxygen. The spin state jump of Cu is stimulated to produce more unpaired electrons. Spin-polarized electrons undergo rapid exchange with oxygens, promoting the protonation of oxygen molecules. In addition, the formation of stable chlorapatite in the OH-channel of HAP imparts excellent shielding properties to the material. The unique thin lamellar and more active electrode storage charge surface give it some electron storage capacity, providing good electrochemical cathodic protection for iron substrates. As a result, the impedance value of Cu-HAP as an anticorrosion material was improved by 501.6% compared with that of epoxy resin. The anticorrosion study of transitionmetal-based inhibitors based on the 3d orbital electronic structure depends on spin-dependent electron transfer. This work provides some insight into the development of the corrosion protection field.

“…In the previous research of our group, it was also confirmed that ZnO-based DMS could be used as an effective corrosion inhibitor to enhance the protection of coatings on ferrous substrates. 14 In studying magnetic metal-doped ZnO nanosolid solutions, Xue 15 et al found that the Lorentz force generated by the micromagnetic field can control the anode electrons to achieve the effect of inhibiting corrosion. What is more, the application of ZnO-based binary/multiple nanomaterials in photocatalysis is also very compelling.…”

The micromagnetic field of magnetic materials helps to improve the anticorrosion properties, so magnetic enhancement measures may bring considerable corrosion inhibition ability. Based on the magnetic generation mechanism of ZnO, the concentration of oxygen vacancy in the crystal lattice was regulated by the doping of magnetic metal Co, the introduction of nonmetallic N, and light treatment, so as to achieve a gradual increase in magnetism. The increased magnetism meant that micromagnetic fields could control electron transport to a greater extent, slowing the rate of corrosion. Moreover, an external magnetic field was applied to the corrosion system and resulted in the formation of a dense secondary protective film on the surface. Results showed that for the corrosion resistance of Co/N codoped ZnO (CNZO) dilute magnetic solid solutions (DMSs), the composite impedance value increased by 1204.0% compared to the pure epoxy coating, and the impedance value increased again by 4100 ohm·cm2 after the application of an external magnetic field and is 5.73 times that of ZnO. This work also confirmed that the magnetic properties of ZnO-based DMSs were positively correlated with the corrosion resistance, which provided guidance for the design of corrosion inhibition materials in other systems.

“…Currently, most researchers have tried to solve these problems by compounding the ZnO material with other materials − or by designing combined structures. , Although these methods can provide excellent corrosion inhibitors, they cannot optimize the properties of the ZnO material. However, elemental doping makes it possible. − …”

Mixed-valence element-doped compounds have attracted great interest due to their unique chemical properties. Here, mixed-valence cerium-doped zinc-oxide solid solution (ZCOSS) material with a single-port hollow columnar structure was prepared under inorganic aqueous conditions, which could effectively inhibit the oxygen-absorbing corrosion of the metal. As a result of the synergistic valence cycling effect of variable-valence cerium and the molecule of zinc oxide and the adsorption effect of the hollow columnar structure, the corrosive environment was hypoxic, the charge transfer was hindered, and the generation of corrosion product was limited. In addition, the doping of cerium changed the energy band structure of the zinc oxide material, making it possible for photoelectrochemical cathodic protection of steels. Thus, the corrosion inhibition efficiency of the ZCOSS composite system is approximately 14 times that of epoxy resin and 5.5 times that of the ZnO composite system.
