Eminently Enhanced Anticorrosion Performance and Mechanisms of X-ZnO (X = C, N, and P) Solid Solutions

Abstract

Nonmetal (C, N, P) doped zinc oxide solid solutions (ZnO SSs) prepared through one-step calcination method exhibited novel anticorrosion capability. The anticorrosion property was identified by electrochemical impedance spectroscopy and polarization curve technique. The maximal impedance belonged to C-ZnO SS, which was 12 times higher than pure ZnO materials. Then, a synergistic anticorrosion mechanism was proposed: the photoelectron flow suppression effect and the self-cohering process formed by doping. The tiny particle size as well as the minor zeta-potential of X-ZnO SSs eminently promoted the intermolecular cohesion and the formation of the compact surface automatically. Moreover, the photocatalytic experiments successfully verified the product and the corrosion inhibition effectiveness of the photoelectrons. Additionally, a positive correlation conclusion between the anticorrosion performance and the photocatalytic performance of the X-ZnO SSs was obtained. Consequently, developing the self-cohering anticorrosion materials is of crucial industrial application prospect and value.

Anticorrosion Performance and Application of a Mixed-Valence Mn0xMn2+0.05–xZn0.95O Solid Solution Induced by Magnetic Doping

“…Figure c shows the typical 1021.2 and 1044.3 eV for Zn 2p 3/2 and Zn 2p 1/2 of ZnO spin–orbital peaks, respectively. The slight shift of the peaks toward the higher binding energy came mainly from the impact of Mn, resulting in the formation of the Zn–O–Mn bond . The special peaks at 1019.0 and 1042.7 eV of 5MZO-5 DMS matched with Zn 2p 3/2 and Zn 2p 1/2 , illustrating that, partially, the Mn 2p ion replaced the Zn 2p ion in the lattice .…”

“…Since the electrochemical properties of zinc oxide can be altered by solid-solution doping methods, the doped ZnO solid solution may make a difference in the field of corrosion protection. In our previous researches, the nonmetal-doped ZnO material displayed better anticorrosion performance, especially the C–ZnO solid solution . Through metal doping, it was proposed that magnetism had an effect on the improvement of the anticorrosion property, which stimulated the exploration and interest in the application of magnetic solid-solution doping technology in the field of anticorrosion.…”

After doping with Mn ions, the enlarged oxygen storage capacity caused by increased crystal defects of ZnO and the generation of magnetism provided ideas in developing the electrochemical corrosion protection.…”
