Ievgenii S. Physico-chemical, catalytic and sensor properties of Pd-containing nanosized materials based on SnO2

The thesis is devoted to establish relationship of characteristics of H2 sensors based on nanosized SnO2 materials doped by additives of Pd with physico-chemical properties and catalytic activities in the reaction of H2 oxidation of these nanomaterials. Optimal temperature conditions of formation of the nanosized SnO2 based materials are determined and the temperature conditions of creating sensors based on Pd/SnO2 were proposed. The catalytic activity of Pd/SnO2 nanomaterials in the reaction of hydrogen oxidation and kinetic of this reaction were studied. It was shown that maxima of the sensor sensitivity to H2 are observed for samples containing 0,016% and 0,09% Pd with average particle size of 14 and 10 nm.
