功能高熵氧化物（Mg0.2Co0.2Ni0.2Cu0.2Zn0.2）O因其独特的性能而受到人们的广泛关注。通常需要高温（约1000 °C）烧结以形成单相（Mg0.2Co0.2Ni0.2Cu0.2Zn0.2）O。本文建立了多元醇-淬火法合成（Mg0.2Co0.2Ni0.2Cu0.2Zn0.2）O的工艺。利用多元醇法得到的无机-有机杂化化合物中金属元素分布均匀的特点，在800 °C淬火后可得到单相HEO。
Functional high-entropy oxide (HEO) (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)O has attracted great attention due to its unique properties. High temperature (∼1000 °C) sintering is generally required to form the single-phase (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)O. In this work, a polyol process followed by quenching is established to synthesize (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)O. Benefiting from the homogeneous distribution of metal elements in the inorganic-organic hybrid compound obtained from polyol process, a single-phase HEO can be achieved after quenching at 800 °C.
