In this work, Cerium Nickel nanocomposite was synthesized and investigated as photocatalyst. Co-precipitation method was used successfully to synthesize Ce-Ni oxides. Couple of characterization techniques such as XRD (powder X-ray Diffraction), FESEM (Field Emission Scanning Electron Microscope), UV-Vis spectroscopy, FTIR (Fourier Transform Infrared spectroscopy) were used to explore the structure, size and morphology of the synthesized photocatalyst. The nanocomposite particle size was average out to be approximately 25–30 nm. To evaluate the photocatalytic efficiency of Ce–Ni nanocomposite, Methylene blue (MB) dye, a model organic compound, was degraded under visible light. To estimate the dye degradation efficiency of nanocomposite, UV/Vis spectroscopy was used, and the results showed 87% Photodegradation of organic pollutant in 3 h. The results illustrate usefulness of Ce nanocomposite with nickel for photocatalytical degradation of organic pollutant under exposure of visible light.

用于通过光催化降解亚甲基蓝的氧化铈纳米复合材料的合成和表征
在这项工作中，合成了铈镍纳米复合材料并作为光催化剂进行了研究。共沉淀法成功地合成了Ce-Ni氧化物。使用XRD（粉末X射线衍射）、FESEM（场发射扫描电子显微镜）、UV-Vis光谱、FTIR（傅里叶变换红外光谱）等表征技术来探索合成光催化剂的结构、尺寸和形貌. 纳米复合材料的平均粒径约为 25-30 nm。为了评估 Ce-Ni 纳米复合材料的光催化效率，在可见光下降解了一种模型有机化合物亚甲蓝 (MB) 染料。为了估计纳米复合材料的染料降解效率，使用紫外/可见光谱，结果显示 3 小时内有机污染物的光降解率为 87%。
