| 中文摘要 | the sno2 material prepared by sol-gel method was modified by thiourea solution in different concentrations (0.05, 0.1 and 0.2 mol dm(-3)). then the structure and the average grain size of the sno2 material were investigated by x-ray power diffraction. in order to understand the nature of the species on the sno2 surfaces, the thermal gravimetric and differential thermal analyzer (tg-dta) and ir spectra of these modified and unmodified sample were taken. the result indicates that the stability of oxygen adsorbed on thiourea-modified surface was improved and the amount of surface hydroxyl groups adsorbed on this grain surface was decreased. the thiourea adsorbed on sno2 grain surface is translated to so42- after sintered at 600 degrees c. so42- species stabilize the resistance of the sno2 sensor.
