摘要：
Porous alpha-Fe2O3 nanobelts have been prepared via a solvothermal route and subsequent calcination. The as-prepared nanostructure was characterized by XRD, FESEM, TEM, N-2 adsorption-desorption isotherms, etc. The alpha-Fe2O3 nanobelts presented obvious porous structures with the length of ca. 1 similar to 2 mu m, width of ca. 200 similar to 350 nm and thickness of ca. 30 similar to 60 nm. It was found that the assistance of inorganic additives played an important role in the shape control of alpha-Fe2O3 nanostructure. The gas-sensing performance of the fabricated sensor based on alpha-Fe2O3 nanobelts sample was also investigated, and the response towards 1000 ppm acetone can reach 24.4. In addition, the gas-sensing conductive mechanism of the sensor was also proposed.
