One-step Route to Single-crystal (gamma)-Mn3O4 Nanorods in Alcohol–Water System

A one-step low-temperature alcohol–water thermal route has been developed to synthesize single-crystal (gamma)-Mn3O4 nanorods with diameters of 50–120 nm, and lengths of up to several tens micrometers. high-resolution transmission electron microscopic observations show that the axial direction of the as-prepared nanorods is perpendicular to the normal direction of the (101) lattice planes of the tetragonal (gamma)-Mn3O4.
