  • Version of Record online: 28 February 2024
Description unavailable

Based on the experimental results, the photocatalytic anti-corrosion mechanism of S-scheme g-C3N4/PANI heterojunction in this research can be summarized as follows: (i) Excited electrons generated by S-scheme g-C3N4/PANI coating unidirectionally transfer to steel surface, the excited electrons are preferentially consumed during corrosion process due to its more negative reduction potential. (ii) Electron holes were simultaneously generated when the excited electrons transferred to steel, electrons holes can oxidize the surficial water to O2. (iii) Excited electrons can be continuously generated under light irradiation, and therefor provide continuous protection. Thus, the consumption of free electrons on steel surface is greatly diminished, achieving the anti-corrosion purpose. As a result, the efficiency of electron transfer was enhanced, and the anti-corrosion performance was improved.
