Herein, we have developed a facile and one pot synthesis of ternary CeO-AlO@GO nanocomposite via wet chemical method. The structural and morphological characteristics of the synthesized nanocomposite was investigated using UV-DRS, FT-IR, XRD, FE-SEM, HR-TEM, EDX and TGA analysis. The CeO-AlO@GO composite was tested for its ability to photocatalytically degrade Rhodamine B (RhB) under visible light illumination. The influence of various operational parameters such as pH, catalyst dosage and initial dye concentration on the photo degradation was investigated in detail. The synthesized CeO-AlO@GO composite shows greater photocatalytic degradation of RhB (99.0%) under visible light irradiation than the raw CeO, AlO, and GO catalysts and any other reported nanocomposite materials. The recyclability results also demonstrate the excellent stability and reusability of the CeO-AlO@GO nanocomposite. This work will be beneficial in the field of industrial and engineering applications in the degradation of organic pollutants. Also, a study of this kind will definitely stimulate many researches in the recently emerging field of solar-driven water splitting.
在这里，我们通过湿法化学方法开发了一种简便的三元 CeO-AlO@GO 纳米复合材料的一锅合成法。使用 UV-DRS、FT-IR、XRD、FE-SEM、HR-TEM、EDX 和 TGA 分析对合成的纳米复合材料的结构和形态特征进行了研究。我们测试了 CeO-AlO@GO 复合材料在可见光照射下光催化降解罗丹明 B（RhB）的能力。详细研究了各种操作参数（如 pH、催化剂用量和初始染料浓度）对光降解的影响。与原始的 CeO、AlO 和 GO 催化剂以及任何其他报道的纳米复合材料相比，合成的 CeO-AlO@GO 复合材料在可见光照射下对 RhB（99.0%）具有更高的光催化降解性能。循环使用结果也证明了 CeO-AlO@GO 纳米复合材料的出色稳定性和可重复使用性。这项工作将有益于工业和工程应用领域中有机污染物的降解。此外，这种研究肯定会激发太阳能分解水这一新兴领域的许多研究。
