Transparent conducting oxides (TCO’s) have widespread uses as electrodes in solar cells and liquid crystal displays and as heat-reflecting window coatings. The commercial TCO of choice is ITO (tin-doped indium oxide). ITO has a typical conductivity of 1!5]103 S/cm and a transparency 85—90% in thin films (1). In addition to ITO, which has been reviewed (2), a number of promising TCO’s consisting...
Mixed oxides MexCo3−xO4 (Me: Ni or Mg, x = 0–0.9) with a spinel structure were synthesized by precipitation from Me, Co nitrate solutions using (NH4)2CO3 as the precipitating agent subsequent modification of dry precipitate cesium Pechini method and calcination. The samples studied XRD, TPR, TPD methods. Their catalytic activity was in low-temperature (150–350 °C) nitrous oxide decomposition pr...
