Selective Oxidation of Salicylic Alcohol to Aldehyde with O 2 /H 2 using Au‐Pd on Titanate Nanotubes Catalysts

Alcohol oxidation with 100 % selectivity to the aldehyde product (versus acid formation) is achieved at mild conditions by a tandem‐type system where the intermediate species of hydrogen peroxide formation from an O 2 /H 2 mixture are formed and utilised directly over Au‐Pd/Ti‐NT catalysts. In situ reaction of the intermediate species minimises the parallel decomposition of hydrogen peroxide into water, overcoming one of the limitations on the use of hydrogen peroxide as a green oxidant.
