对合成金属氧化物进行各种应用测试对于根据材料性能确定合适的应用领域至关重要。本研究制备了Ni-oxide@ TiO 2核壳材料，并将其应用于混合染料（甲基橙子+罗丹明+亚甲基蓝）的紫外可见光催化降解、CO氧化以及超级电容器等方面。通过场发射扫描电子显微镜、X射线衍射分析、傅里叶变换红外光谱和紫外-可见吸收光谱对其理化性质进行了研究。结果表明，它们的性能是高度依赖于形态，热处理程序，和TiO 2覆盖涂层。
Performing diverse application tests on synthesized metal oxides is critical for identifying suitable application areas based on the material performances. In the present study, Ni-oxide@TiO2 core-shell materials were synthesized and applied to photocatalytic mixed dye (methyl orange + rhodamine + methylene blue) degradation under ultraviolet (UV) and visible lights, CO oxidation, and supercapacitors. Their physicochemical properties were examined by field-emission scanning electron microscopy, X-ray diffraction analysis, Fourier-transform infrared spectroscopy, and UV-visible absorption spectroscopy. It was shown that their performances were highly dependent on the morphology, thermal treatment procedure, and TiO2 overlayer coating.
