摘要:
采用溶胶凝胶法制备了纳米二氧化钛粉末,并与均匀沉淀法制备的纳米二氧化锡粉末复合,制备出纳米TiO2SnO2复合材料.通过硝酸银掺杂制得TiO2Ag+,TiO2SnO2Ag+(Ti/Sn=2∶1),TiO2SnO2Ag+(Ti/Sn=3∶1)三类气敏材料,采用静态配气法测试了气敏元件对乙醇,甲醇和甲醛的气敏特性.实验结果表明,TiO2复合SnO2并掺杂适量Ag+能显著改善TiO2的气敏性能,其中Ti∶Sn=2的复合材料气敏性能优于Ti∶Sn=3的复合材料.
Abstract:
The nanotitanium dioxide powder was prepared by the solgel and composed with the nanotin dioxide powder prepared by the sluggish precipitation. Three types of gas sensitive materials, which were TiO2Ag+, TiO2SnO2Ag+(Ti/Sn=2∶1) and TiO2SnO2Ag+(Ti/Sn=3∶1), were prepared with doping the silver nitrate. The gassensing properties of the gas sensors to ethanol, methanol and formaldehyde were tested by the Static Gas Distribution Act. The results show that the gas performance of TiO2SnO2 composites doped by appropriate Ag+ improve obviously,and the composite of chemical molar ratio 2 is more sensitive than the composite of chemical molar ratio 3.
