Facile Synthesis of Porous SnO(2) Spherical-Like Aggregates and Their Gas Sensing Property

• Porous spherical-like aggregates synthesis of SnO(2) crystals was achieved via a hydrothermal process in the mixed solvents of water and ethanol. The products were characterized by powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy and Raman measurements. Morphological characterization showed that porous spherical-like aggregates were composed of short nanorods. Three main peaks broadening and shifting to high wavenumber in Raman spectrum implied that the components of the products had a smaller size. The result of the gas sensing measurement indicated that porous spherical-like aggregates had excellent ethanol gas sensing property compared to that of nanoparticles.
