Abstract

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 O₂/H₂ mixture are formed and utilised directly over Au-Pd/Ti-NT catalysts. Insitu 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. In the mix for selective oxidation: Insitu formation and utilisation of intermediate oxidising species from O₂/H₂ mixtures in a tandem-type system minimises the parallel decomposition of hydrogen peroxide with 100% selectivity to the aldehyde product.
