Abstract

To figure out the behavior of benzotriazole (BTA) loaded in CeO₂ nanocontainers during long term anticorrosion, three kinds of CeO₂ spheres were used: hollow spheres (HSs), double-shell hollow spheres (DHSs), and solid-mesoporous spheres (SSs). The BTA loading and releasing situations were checked, and CeO₂-HSs exhibited the largest BTA loading amount of 12.5 wt%, forming by both chemical and physical adsorption. The highest BTA loading in CeO₂-HSs may be attributed to its hollow structure and more Ce³⁺ sites (39 %) for BTA anchoring. Thus, CeO₂-HSs@BTA exhibited an excellent long-term anticorrosion in epoxy coating for low carbon steel protection, showing no rusting after 40 days of salt spray experiment.
