摘要：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.
