The thesis is dedicated to the synthesis, comprehensive material science and some sensing properties of SnO2-MetOx oxide systems (where MetOx are IVB and IIIB metal oxides). The study was performed in comparison with blank SnO2, and SnO2 doped with noble metals (Pd, Pt, Rh and their binary mixtures). Results of 8 ex-situ (TEM, HRTEM, XRD, FTIR, UV-Vis, BET, XPS and element analysis), 5 in-situ (TGA, MS-analysis, DRIFT, TXRD, TPR) techniques and sensing properties characterization (DC measurements as a function of temperature and gas composition) are discussed regarding surface chemistry of SnO2 sensing phenomenon. The special attention is paid to the role of surface hydroxyls in the processes related with conductivity change of semiconducto...
