通过一种简单可控的电沉积-热处理方法，成功地在钛衬底上制备了层次化的支化MoO_3纳米结构。XPS和拉曼光谱结果表明，这些支化的MoO_3纳米结构中存在一些氧空位。磁性测量表明，所制备的支化MoO_3纳米结构在室温下表现出铁磁行为。观察到的室温铁磁性主要归因于样品表面的氧空位。
Hierarchically branched MoO3 nanostructures on Ti substrates were successfully prepared via a simple and controllable electrodeposition-heat-treatment method. XPS and Raman results indicate that these branched MoO3 nanostructures possess some oxygen vacancies. The magnetic measurements show the prepared branched MoO3 nanostructures exhibit ferromagnetic behaviour at room temperature. The observed room-temperature ferromagnetism can be mainly ascribed to the oxygen vacancies on the surface of the samples.
