英文摘要	In this paper, the highly sensitive n-butanol sensors with high selectivity have been successfully fabricated based on spindle shaped alpha-Fe2O3 nanorods modified by Au nanoparticles (Au NPs). Spindle shaped alpha-Fe2O3 nanorods were synthesized by an improved facile hydrothermal method. Uniform Au NPs were deposited on the surface of the as-synthesized alpha-Fe2O3 nanorods by a simple impregnation method. The achieved alpha-Fe2O3 and Au/alpha-Fe2O3 nanorods were analyzed by means of XPS, TEM, EDS, XRD and SEM. The sensing properties of both original and Au-modified spindle shaped alpha-Fe2O3 samples were investigated and discussed. The experimental results indicate that the sensors based on Au/alpha-Fe2O3 nanorods exhibit better responses and selectivity to n-butanol gas than the original alpha-Fe2O3, and the highest response towards 100 ppm n-butanol gas was enhanced from 51 to 177 at the optimal operating temperature of 250 degrees C.
