The study of oxide catalysts by electrical conductivity methods leads to important contributions in the elucidation of the reaction mechanisms taking place on these solids. MoO3-Fe2O3, MoO3-Bi2O3 and V2O5-TiO2 catalysts were prepared with various ratios between the component oxides, and electrical conductivity values in nitrogen, air and hydrogen were determined, showing that they behave as n-type semiconductors. By measuring the electrical conductivity values at constant temperature in three different environments (nitrogen, a reductive atmosphere consisting of a reactant molecule such as methanol, a light alkene or o-xylene, and then in air), it was established that partial oxidation reactions of the reactant molecules take place according to a reduction - oxidation mechanism that implies the action of the lattice oxygen. |
