Poly-crystalline In（OH） 3 nanorods have been successfully prepared via a urea-based precipitation using the colloidal carbon spheres as the templates. After calcinations, the resulted In 2 O 3 nanorods with poly-crystalline structure were fabricated. Structure and morphology of the product were characterized by X-ray diffraction （XRD）, and transmission electron microscopy （TEM）. The possible formation process was schemed. The sensor gas properties towards C 2 H 5 OH and CO were examined.
