摘要

A photocatalytic route for the conversion of lactic acid to acetaldehyde in water is demonstrated. Direct UV photolysis of lactic acid yields CO₂ and ethanol via a radical mechanism. Pt/TiO₂ considerably increases the rate of lactic acid decarboxylation with acetaldehyde, H₂ and CO₂ as the main products. A concerted photodecarboxylation/dehydrogenation mechanism is proposed.
