摘要 The SnO2-x. with different oxygen vacancy concentrations was modified by addling Sm. The modified SnO2-x was investigated by means of X-ray diffraction, X-ray photoelectron spectroscope, and scanning electron microscopy. Its gas-sensing properties to C2H6, C6H14, C2H5OH, CO, and H2 were studied too. The experiment results show that the gas-sensing properties of Sm/SnO2-x depend upon the amount of oxygen vacancies, therefore it is possible to improve gas-sensing properties of doped SnO2 by controlling its concentration of oxygen vacancy.
