Low temperature H2S sensor based on copper oxide/tin dioxide thick film
H2S copper oxide/tin dioxide gas sensors selectivity
2013/12/12
Nanostructured tin dioxide (SnO2) powders were prepared by a sol-gel dialytic process and and the doping of CuO on it was completed by a deposition-precipitation method. The thick film sensors were fa...
