摘要:
In this work, In2O3microspheres with hierarchical nanostructures were successfully synthesized by solvothermal method in the presence of oleic acid and urea. The as-synthesized samples were characterized by X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and high-resolution transmission electron microscopy (HRTEM). The results indicate that the synthesized hierarchical In2O3consists of irregular nanorods. Moreover, the gas sensing properties of as-prepared In2O3hierarchical microspheres were investigated. It was found that the sensor based on such hierarchical nanostructures exhibited high response and good selectivity to NO2at 145℃.
