| Outline of Final Research Achievements |
Chemocatalytic conversion of biomass-derived carbohydrates including glycerol and glucose to lactic acid was studied using a stable and highly active solid catalysts. We found that metallic Pt sites and Lewis acid sites on TiO2-supported Pt nanoparticles are active for aerobic oxidation of glycerol to triose sugars and subsequent transformation of these C3 sugars to lactic acid, respectively. A combination Lewis acid and base sites on niobium-containing mixed oxides is effective for step-wise conversion of glucose to lactic acid that contains isomerization (glucose to fructose), retro-aldol condensation (fructose to triose sugars), and dehydration/isomerization (triose sugars to lactic acid) in water.
