摘要
Monodispersed and uniform single-crystal compass-shaped (80 nm in middle width and 200 nm in length) Mn3O4 (hausmannite) have been successfully prepared in a surfactant solution system by a simple reduction-oxidation method at room temperature and under ambient pressure. The reactions contain two steps: first, Mn2+ is reduced into Mn atoms by gamma-ray irradiation; then, Mn atoms are oxidized into Mn3O4 in air. The possible growth mechanism has also been proposed.
