| Abstract: | The gas sensor was made of nanometer- sized Sn O2 for environmental monitoring.The nanometer- sized Sn O2 particles were prepared by a sol- gel method using inorganic salt as a precursor material and a little additive as a sol forming auxiliary.Different sersitivity and selectivity of different doped nano- Sn O2 gas sersors for some reducing gasses were studied which offers some technical data to develop a new highly sensitive and selective gas sensor for environment detection. |
