Preparation of different shaped α-Fe2O3 nanoparticles with large particles of iron oxide red

Abstract

Using anions (OH⁻, Cl⁻, SO₄²⁻, NO₃⁻ and CH₃COOH⁻) as structure and surface directing agents, α-Fe₂O₃ nanoparticles with quasi cube, parallel hexahedron, irregular sphere, nanosheet and hexagon shapes were successfully prepared by utilizing larger particles of iron oxide red.
