Full textThis work deals with the synthesis and characterization of new materials, more sensitive and more selective, for the detection of pollutants gases. The electric or catalytic response of a sensing material depend on many factors like the grain size, the exposed crystallographic facets, the nature and valence of cations, the presence of oxygen vacancies. The aim of this thesis is the synthesis and characterization on one oxide with different shape in order to study their influence on the detection and catalytic properties of the sensing material. Cobalt ferrite, CoFe2O4 was synthesized by hydrothermal and solvothermal routes. The powders were characterized by thermogravimetric analyses (TGA), X rays diffraction (XRD), transmission electron microscopy (TEM) coupled with energy dispersive spectroscopy (EDS). The testes gases were nitrogen dioxide NO2 and carbon monoxide CO.Nano-octahedron,as small as 20 nm, were obtained by a hydrothermal route, after optimization of temperature, reaction time, and PH of the solutions. The use of cetyltrimethylammonium bromide (CTAB) as a surfactant leads to high purity powders. The grain shape is controlled by the precipitating agent and OH- ions in the reaction medium. Measurements of the electric response of the sensing material show that the grains shape definitively influences the sensitivity as well as the time response of the sensing material. Under oxidative gas (NO2), nanooctahedra of CoFe2O4 have a significantly higher sensibility than grains of same mean size, but without particular shape, as well as much shorter response and recovery times. This higher reactivity is linked to the {111} crystallographic facets, which exhibit octahedral sites. Nanooctahedra of CoFe2O4 showed also good catalytic activity toward the oxidation of CO. Reaction speeds (by specific area unit) are higher for nanooctahedra than for grains with no particular shape.A spherical hierarchical structure of nanooctahedra was obtained by adsorption of the grains at the surface of carbon spheres 200 nm in diameter, followed by their calcination at 350°C
