A novel chemistry strategy has been employed to prepare fiber-like SnO2 by replicating the morphologies and microstructures of natural cotton fibers. X-ray diffraction, electron microscopy, BET, thermal analysis, and infrared spectra were used to characterize the intermediate or final products. The proposed mechanism for formation of the fiber-like SnO2 was discussed. The obtained product was composed of nanoparticles with the average size of 14 nm which interconnected with each other and formed porous microstructures. Because of the small size and special porous microstructures, the obtained fiber-like SnO2 showed high sensitivities to ethanol gas.
