Entirely inorganic polyoxometalate cluster-anion ligands are herein used to entrap and impart heat resistance to metastable metal-oxide based NCs. This is demonstrated by trapping 6-line ferrihydrite NCs that form as intermediates in the spontaneous conversion of β-FeOOH to hematite (α-FeO). The results suggest that polyoxometalate ligation may prove to be a general method for stabilizing metastable phases as the cores of entirely inorganic macro-anion like complexes.
本文采用完全无机的多金属氧酸盐簇阴离子配体来捕获亚稳态金属氧化物基纳米晶并赋予其耐热性。通过捕获在β-FeOOH自发转化为赤铁矿（α-FeO）过程中作为中间体形成的六线水铁矿纳米晶，证明了这一点。结果表明，多金属氧酸盐配位可能被证明是一种稳定亚稳态相作为完全无机大阴离子类配合物核心的通用方法。
