摘要：A hierarchical magnetite (Fe(3)O(4)) nanostructure with coral-like morphology was synthesized by a simple glucose-assisted solvothermal method. The structure consists of tens of twigs with lengths about 1-2 mu m. The root of the nanostructure is composed of random-aggregated particles with sizes of ca. 10 nm, and the twigs were formed from the oriented-aggregation of nanoparticles. During the formation of the hierarchical structure, the glucose played an important role: its derivates coordinated with iron ions to control the nucleation and growth of Fe(3)O(4); and it also acted as a morphology-directing agent.
