catalysts Supported catalysts were obtained by the equilibrium adsorption technique. The solutions for impregnation were prepared by dissolution of the HPAs (PMoV and PMoVBi, 160 mg of each one) in absolute ethanol (3.50 mL). The first step in

(−10–65 °C), the reaction rate was found to be zeroth order with respect to CO and 0.2–0.3 order with respect to O 2 over Au/TiO 2 and Au/Co 3 O 4 . For the α-Fe 2 O 3 supported catalyst, on the other hand, the reaction orders for both reactants were

can be reused many times without significant loss of activity [ 1 – 6 ]. Such supported catalysts can be prepared by insertion of a ligand to an inert solid material and then using it as heterogenized ligand for the preparation of a supported metal
