In this work, urchin-like In₂O₃ microspheres were fabricated using a solvothermal method in the presence of SOS (sodium dodecyl sulfonate) and urea. The as-synthesized samples were characterized using X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM). The results indicate that the synthesized urchin-like In₂O₃ microspheres were constructed by nanorods. Moreover, the gas sensing properties of as-prepared products were investigated. It was found that the sensor based on such novel urchin-like In₂O₃ microspheres exhibited high response and good selectivity to O^-3.
