Paper Title:
Nanocrystalline Tin Oxide Thick-Film Gas Sensor for H2S Detection
  Abstract

Nanocrystalline thick-film gas sensor was fabricated by screen printing method with CuO-doped tin oxide powder synthesized by hydrothermal method. Average grain size of the CuO-doped tin oxide powders was typically below 10 nanometers and the thick-films had a narrow grain size distribution typically below 50 nanometers. Effect of the amount of CuO on the sensing properties was investigated and the optimal value was found to be 3 wt%. The nanocrystalline CuO-SnO2 thick-film gas sensors were more sensitive to H2S than those based on commercial micro SnO2 powders, which were attractive to the detection of low concentrations of H2S gas at relative low temperatures.
