1.25 – 5wt%Pt/Al2O3, 1.25 – 5wt%Pd/Al2O3, 1wt%Pd/TiO2, 1 – 5wt%Pd/TiO2-NF, 1.25wt%Pt+1.25wt%Pd/Al2O3, 5wt%Pt/SiO2, 5wt%Pt/C catalysts were synthesised and tested in the selective oxidation of 1,2-propanediol by molecular oxygen. It was found that all catalysts were active in alkaline water solutions; lactic acid was obtained as the main product of the reaction. The conversion of 1,2-propandiol and the yield of lactic acid depended on the content of active metal in the catalysts. The most active for the oxidation of 1,2-propandiol were palladium-containing catalysts supported on TiO2 nanofibers (Pd/TiO2-NF). The highest 1,2-propanediol conversion (100 %) and lactic acid yield (96 %) were obtained using the 5wt%Pd/TiO2-NF catalyst at the following oxidation parameters: c0(1,2-propanediol) = 0.3 mol/L, P(O2) = 1 atm, n (1,2-propanediol)/n (Pd) = 500 mol/mol, t = 60 °C, c0(NaOH) = 1.5 mol/L.
