Photocatalytic Synthesis of Acetaldehyde by Selective Oxidation of Ethanol on RuO<sub>x</sub>-VO<sub>x</sub>/TiO<sub>2</sub>

Photocatalytic Synthesis of Acetaldehyde by Selective Oxidation of Ethanol on RuO<sub>x</sub>-VO<sub>x</sub>/TiO<sub>2</sub>

The gas-solid photocatalytic partial oxidation of ethanol to acetaldehyde on monometallic RuOx/TiO2 and bimetallic RuOx-VOx/TiO2 catalysts has been studied in a fluidized bed photoreactor at high illumination efficiency. For RuOx/TiO2, by increasing ruthenium loading ethanol conversion decreased fro...
