    摘要:

    高熵氧化物作為一種新型的氧化物體系，打破了傳統(tǒng)合金相互摻雜的設(shè)計(jì)理念，由五種或五種以上的氧化物相互固溶得到，因其獨(dú)特的結(jié)構(gòu)和潛在的應(yīng)用價(jià)值而受到廣泛關(guān)注。本研究采用簡(jiǎn)易的固相反應(yīng)法制備了(FeCoCrMnCuZn)3O4高熵氧化物粉體，采用XRD、SEM、TEM、XPS等方法對(duì)其進(jìn)行表征。結(jié)果表明，隨著煅燒溫度的升高，F(xiàn)e2O3、Cr2O3、MnO2、CuO和ZnO相繼固溶進(jìn)尖晶石結(jié)構(gòu)中；最終，在800℃煅燒2h可得到單一尖晶石結(jié)構(gòu)（面心立方，F(xiàn)d-3m）的(FeCoCrMnCuZn)3O4氧化物，且各元素在晶粒內(nèi)分布均勻，為典型的高熵氧化物特征。對(duì)合成的高熵氧化物(FeCoCrMnCuZn)3O4粉體進(jìn)行電化學(xué)性能分析發(fā)現(xiàn)，當(dāng)電流密度為1 A/g時(shí)，質(zhì)量比電容為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.
