“…In that class of materials, In2O3 is not as much studied as SnO2 and WO3 even if it shows interesting properties. It was reported that it shows good performance for the detection of CO or methane [1] but its high selectivity towards oxidizing gases (e.g., NO2 or O3) at low temperatures [2,3] is its most prominent and outstanding property. Although In2O3 has been investigated over two decades, the sensing mechanism is not fully understood.…”

Abstract:In this study, the electrical characteristics and surface reactions of three different kinds of In2O3 based gas sensors were investigated under CO exposure in dry and humid air by using DC electrical resistance measurements and Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). For the first time one gains insight into the surface reactions during the exposure to CO and humidity. The sensors show different behavior on the baseline in humidity depending on the material which is due to different kinds of OH-groups. The resistance change under CO and humidity exposure are additive and the molecules compete for the same reaction partner confirmed by the spectroscopy results. Through isotopic exchange experiments, different adsorbates could be identified.

“…Physicochemical properties, structure and applications of molybdenum(VI) oxide and indium(III) oxide are well known [2][3][4][5][6][7]. MoO 3 , In 2 O 3 and In 2 (MoO 4 ) 3 formed as a result of a reaction between the former two, are components of active and selective catalysts of different processes of oxidation of organic compounds, e.g.…”

Thermal stability of a compound forming in a binary system MoO 3 -In 2 O 3 was investigated by DTA/TG, XRD and SEM methods in this study. For the first time, the diagram of phase equilibria established in the whole range of concentrations of this system's components has been constructed. The temperature and concentration ranges of the components of MoO 3 -In 2 O 3 system in which the compound In 2 (MoO 4 ) 3 co-exists in solid state with MoO 3 or In 2 O 3 or with the liquid were determined. The composition and melting point of the eutectic mixture consisting of In 2 (MoO 4 ) 3 and MoO 3 were found.
