A novel and effective strategy for electro-oxidation of ethanol to acetaldehyde
2016
Abstract For taking full advantages of electrochemical synthesis and high selectivity of peroxydisulfate for oxidation of alcohol to aldehyde, the electrocatalyst Ti-TiN x O 2 − x -Pt and electrolysis-separation device were constructed. The synergetic effect between the Ti-TiN x O 2 − x -Pt with the suitable catalytic performance for electro-oxidation of HSO 4 − to peroxydisulfate and the electrolysis-separation device with the rapid separation of the acetaldehyde from the reaction system dramatically enhances the catalytic performance of Ti-TiN x O 2 − x -Pt for the indirect electro-oxidation of ethanol to acetaldehyde. The current efficiency for generation of acetaldehyde reaches 88.9%, higher than those reported in the literature. This method also possesses easy operation, high stability and recycling functionality.
