Hydrothermal Synthesis and Characterization of Single-Crystalline 𝛼-Fe2O3 Nanocubes

Hydrothermal Synthesis and Characterization of Single-Crystalline 𝛼-Fe2O3 Nanocubes

Single-crystalline 𝛼-Fe2O3 nanocubes were successfully obtained in large quantities through a facile one-step hydrothermal synthetic route under mild conditions. In this synthetic system, aqueous iron (III) nitrate (Fe(NO3)3⋅9H2O) served as iron source and triethylamine served as precipitant and alk...
