摘要 在金红石结构的TiO2中掺入质量分数为10%的Nb2O5,0.5%的Sb2O3和2%的In,可以充分发挥添加剂的强催化作用,使敏感器件在空气中的阻值降低到10MΩ以下,并在一定程度上提高器件灵敏度,响应三甲胺(TMA)气体的最低下限体积分数为1×10-6. Doping Nb_2O_5(10?%),Sb_2O_3(0.5?%) and In(2?%),as additives on rutile TiO_2,can decrease the resistance (R_a) to below 10?MΩ and partly improves the sensitivity of element,owing to the strong catalysis of additives.The minimum concentration of TMA the sensor sensitive to in experiment is 1×10^(-6).
