Green oxidation of alcohols to carbonyl compounds by heterogeneous photocatalysis.

The selective conversion of alcohols to carbonyl compounds is essential for the preparation of fragrances, food additives, and many organic intermediates. This transformation is carried out by catalytic processes that are of fundamental importance in synthetic chemistry. Catalytic oxidation has long been carried out in environmentally harmful organic solvents (often chlorinated ones) at high te...
