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.
对合成的金属氧化物进行多种应用测试，对于根据材料性能确定合适的应用领域至关重要。在本研究中，合成了氧化镍@二氧化钛核壳材料，并将其应用于紫外光和可见光下光催化混合染料（甲基橙+罗丹明+亚甲基蓝）降解、一氧化碳氧化及超级电容器。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物理化学性质进行了研究。结果表明，它们的性能高度依赖于形态、热处理过程和二氧化钛覆盖层涂层。
