高熵氧化物由于其独特的结构和潜在的应用前景而受到越来越多的关注。采用固相反应法合成了M3 O 4（M=FeCoCrMnMg）高熵氧化物粉末。用不同的方法对粉末进行了表征。此外，采用包覆法制备了M3 O 4/Ni泡沫（M3 O 4/NF）电极，并对其超级电容器性能进行了研究。结果表明，随着煅烧温度的升高，Fe 2 O3（H）/Co 3 O 4（S）/Cr2 O3（E）和Mn 2 O3（B）依次固溶于尖晶石结构的晶格中。M3 O 4粉体经900 °C煅烧2 h后，得到单一的尖晶石结构（FCC，Fd 3 m，a= 0.8376nm），Fe、Co、Cr、Mn、Mg元素分布均匀，具有典型的高熵氧化物特征。此外，在1 mol/L KOH电解液和1 A g电流密度下，M3 O 4/NF复合电极的质量比电容为193.7 F g，表明M3 O 4高熵氧化物可作为超级电容器电极材料的候选材料。
High-entropy oxides have attracted more and more attention due to their unique structures and potential applications. In this work, M3O4(M=FeCoCrMnMg) high entropy oxide powders were synthesized by a facile solid-state reaction method. The powders were characterized by different methods. Furthermore, M3O4/Ni foam (M3O4/NF) electrode was prepared by a coating method, followed by the investigation of its supercapacitor performance. The results showed that, with the increase of calcining temperature, Fe2O3(H)/Co3O4(S)/Cr2O3(E) and Mn2O3(B) dissolved successively in the crystal lattice of spinel structure. After M3O4 powders being calcined at 900 °C for 2 h, single spinel structure (FCC, Fd3m, a=0.8376 nm) was obtained with uniform distribution of Fe, Co, Cr, Mn, and Mg elements, the typical characteristic of high entropy oxide. In addition, the mass specific capacitance of M3O4/NF composite electrode is 193.7 F g, with 1 mol/L KOH as electrolyte and 1 A g as current density, which indicated that the M3O4 high entropy oxide can be considered as a promising candidate for the electrode material in the field of supercapacitor applications.
