摘要:
采用溶胶凝胶法制备了TiO2SnO2复合纳米材料,以其为基底进行Ag+掺杂作为气敏材料，制备成旁热式气敏元件，研究了无光照和313 nm紫外光照下元件对有机挥发气体甲醇和乙醇的气敏特性.结果表明：紫外光照可使半导体元件的电导显著增大，提高元件对醇类有机挥发性气体的灵敏性，240 ℃时灵敏度为62，是无光照时的1.5倍；在乙醇气体浓度为4.5×10-6 mol/L时灵敏度达到26.5，而无光照时仅为9.5.
Abstract:
TiO2 and SnO2 composite nano materials were prepared by solgel and doped by Ag+, then were made as the heatertype gas sensors. The gassensing properties of gas sensors to volatile organic gases (VOCs) such as methanol and ethanol without light irradiation and under 313 nm Ultraviolet Light were studied respectively. The results show that UV irradiation can evidently raise conductivity of semiconductor and improve the sensitivity. The sensitivity for ethanol reach 62 at 240 ℃ which is 1.5 times of the value measured without light irradiation.And the sensitivity is 26.5 for 4.5×10-6 mol/L ethanol under UV while no light irradiation the value is only 9.5.
