This paper deals with chemoresistive behavior of hexagonal YMnO 3 produced by gel combustion. Stoichiometric, defective and doped compositions were studied and both reducing (CO) and oxidizing test gases (NO x ) were used. The materials were characte

An artificial olfactory system (AOS) for the detection of highly toxic gases in air is presented. The AOS is based on YCoO 3 perovskites. Previous researches of the authors already showed that YCoO 3 is characterized by a satisfactory sensitivity tow

In this work, a set of models able to predict the behavior of tin oxide (SnO 2 ) sensors during chemical and thermal transients is presented. These models are obtained through simplification of more complex physicochemical ones, taking into account b

YCoO3 perovskite powder was prepared by the classical sol–gel method, which was extended to the preparation also of non stoichiometric materials or samples containing platinum or palladium, incorporated either during synthesis or a posteriori throu

YCoO3 perovskite powder was prepared by gel combustion method, which was extended to the preparation also of non-stoichiometric materials and samples containing Pt or Pd. This preparation route allows for increasing the surface area and hence the sur

Metal oxide gas sensors (MOXs) are widely used in olfactory electronic systems for their high sensitivity and low-cost. These sensors modify their conductivity in presence of oxidizing and reducing gases, and their performance is strictly dependent o

Zirconia-supported vanadium oxide catalysts were prepared by equilibrium adsorption in acid (pH 2.7) or basic (pH 10) conditions using hydrous zirconium oxide and an aqueous solution of ammonium metavanadate. The samples, containing vanadium up to 22

The catalytic combustion of some volatile organic compounds (VOCs) has been investigated over LaMnO3 and LaCoO3 perovskite-type oxides. Redox titration has shown that cobalt is present in LaCoO3 exclusively in the 3+ oxidation state whereas LaMnO3 co

Perovskite LaFeO 3 and derived materials La (1− ϵ ) FeO (3−1.5 ϵ ) with ϵ =0.1, 0.2, 0.3 have been prepared as polycrystalline powders by thermal low-temperature decomposition of La and Fe nitrates, a method which ensures a high surface area.
