论文摘要
在这项工作中，准备了制备铁液纳米复合cuxce $ _ {0.3-x} $ ni $ _ {0.7} $ fe $ _2 $ _2 $ o $ $ _4 $（其中：x = 0，0.05，0.15，0.15，0.2，0.2，2.25）是使用自动燃烧技术（用于燃料的燃料）和citiquie undique and Idic and Indique and Idic and Idic and Idic and Incile and Incirique and Idique and Idique utriq usriq usriq usriq utriq usriq utriq utriq usriq utriq utrirecique。 X射线衍射（XRD），发射场扫描电子显微镜（FE-SEM）和能量分散X射线分析仪（EDX）测试的结果表明，所制备的化合物具有以面部为中心的立方体结构（FCC）多晶体结构（FCC）polyCryStalline，并且该晶格的成分增加，并增加了coper is的组合，并降低了copper Is的含量，并降低了copers的组合。多孔及其分子是球形的，除了合成该化合物的合成外，没有其他元素，表明它具有很高的纯度，并且该组合对二氧化氮（无$ _2 $）气体具有很高的敏感性，如气体检测设备所确定的。
In this work, the ferrite nanocomposite CuxCe$_{0.3-X}$Ni$_{0.7}$Fe$_2$O$_4$ is prepared (where: x = 0, 0.05, 0.1, 0.15, 0.2, 0.25) was prepared using the auto combustion technique (sol-gel), and citric acid was utilized as the fuel for Auto combustion. The results of X-ray diffraction (XRD), emitting field scanning electron microscope (FE-SEM), and energy dispersive X-ray analyzer (EDX) tests revealed that the prepared compound has a face-centered cubic structure (FCC) polycrystalline, and the lattice constant increases with an increase in the percentage of doping for the copper ion, and decreases for the cerium ion and that the compound is porous, and its molecules are spherical, and there are no additional elements present other than those used in the synthesis of the compound, indicating that it is of high purity, and the combination has a high sensitivity to Nitrogen dioxide (NO$_2$) gas, as determined by the gas detecting equipment.
