| 摘 要： | 采用简易的固相反应法制备了(FeCoCrMnCuZn)_3O_4高熵氧化物粉体,采用XRD、SEM、TEM、XPS等方法对其进行表征。结果表明,随着煅烧温度的升高,Fe_2O_3、Cr_2O_3、MnO_2、CuO和ZnO相继固溶进尖晶石结构中;最终,在800℃煅烧2 h可得到单一尖晶石结构(面心立方,Fd-3m)的(FeCoCrMnCuZn)_3O_4氧化物,且各元素在晶粒内分布均匀,为典型的高熵氧化物特征。对合成的高熵氧化物(FeCoCrMnCuZn)_3O_4粉体进行电化学性能分析发现,当电流密度为1 A/g时,质量比电容为152.9 F/g。

| Abstract: | As a new type of oxide system, high-entropy oxide breaks through the design concept of mutual doping of traditional alloys. It is obtained by solid solution of five or more oxides. It is widespreadly concerned due to its unique structure and potential application value. In this work, spinel-structured (FeCoCrMnCuZn)3O4 high-entropy oxidepowders were prepared by a facile solid-state reaction method and characterized by XRD, SEM, TEM and XPS. The results show that, with the increase of calcining temperature, Fe2O3, Cr2O3, MnO2, CuO and ZnO are successively dissolved into the spinel structure. Finally, (FeCoCrMnCuZn)3O4 oxide with a single spinel structure (face-centered cubic, Fd-3m) was obtained by calcining at 800 °C for 2 h. Fe, Co, Cr, Mn, Cu and Zn are uniformly distributed in the (FeCoCrMnCuZn)3O4 grains, which is a typical feature of high-entropy oxide. When the current density is 1 A/g, the mass specific capacitance of the synthesized (FeCoCrMnCuZn)3O4 high-entropy oxide powders is 152.9 F/g. |
