Abstract
Zinc vanadium oxide (ZVO) with a special alternated structure is a significant photoelectric material, so exploring atomic regulation and light processing technology to improve its electrical properties is an interesting scientific issue of potential value. Herein, a Zn3(VO4)2 crystal with a self-assembled 3D micro–nano-spherical structure was synthesized through accurately controlling the conditions of hydrothermal reaction and calcination, which increased the corrosion resistance by 429.8% compared with pure epoxy resin. After that, hydroxyl groups were successfully constructed on the crystal surface by light modification to further improve the visualized anticorrosion effect (increased by 743.5%). All of these were due to the realization of the interlayer structure, defect construction, and chloride-ion replacement under the structure-oriented effect, as well as zinc–vanadium bimetal protection. Consequently, the heat treatment, light modification, and electrochemical performance we reported in this paper, and the practicability in the iron-anticorrosion industry, were creatively reflected in the ZVO crystals.
