In this endeavor, ultra-fine Ce oxide QDs were synthesized via an in-situ approach which itself was divided into two methods exploited to synthesize QDs on the GO nanosheets. Afterward, the obtained product was loaded into the Epoxy (EP) structure and finally applied on the surface. The results affirmed the presence of Ce oxide QDs and the quantum confinement effect in both samples. FT-IR analysis confirmed the presence of different functional groups such as CC and CH. UV–Vis outcome showed the interaction of GO nanosheets and CeO₂ QDs. The morphology of the surface, QDs distribution on the GO nanosheets, shape, and particle sizes were explored using FESEM and HR-TEM. Lastly, the corrosion suppression of different coatings—pure EP, GO-only-containing EP, or EP loaded with quantum-dots-deposited GO synthesized by two methods—were compared and discussed in detail with the help of EIS and salt spray methods. The result showed that, in the scratched samples, the maximum R_ct of 45,080 ohm.cm² was reached when the QDs-modified GO, attaining via the first method, was employed. The overall result denoted the superior performance of the QDs-modified GO nanosheets embedded in the EP coating—most specifically the one synthesized with the first method.

在这项努力中，超细氧化铈量子点是通过原位方法合成的，该方法本身分为两种用于在 GO 纳米片上合成量子点的方法。之后，将获得的产品加载到环氧树脂（EP）结构中并最终应用于表面。结果证实了两个样品中氧化铈量子点的存在和量子限制效应。FT-IR 分析证实了 C C 和 C H等不同官能团的存在。UV-Vis 结果显示 GO 纳米片和 CeO ₂的相互作用量子点。使用 FESEM 和 HR-TEM 探索了表面的形态、GO 纳米片上的 QD 分布、形状和粒径。最后，在 EIS 和盐雾法的帮助下，对不同涂层的腐蚀抑制进行了比较和详细讨论 - 纯 EP、仅含 GO 的 EP 或负载有通过两种方法合成的量子点沉积 GO 的 EP。结果表明，在划痕样品中，当采用通过第一种方法获得的 QDs 修饰的 GO 时，达到了 45,080 ohm.cm ²的最大 R _ct。总体结果表明嵌入 EP 涂层中的 QD 修饰的 GO 纳米片具有优异的性能——尤其是用第一种方法合成的那种。
