“Double‐Peak” Catalytic Activity of Nanosized Gold Supported on Titania in Gas‐Phase Selective Oxidation of Ethanol

Abstract

Seeing double: Au/TiO2, in contrast to Au supported on silica and alumina, shows “double-peak” catalytic activity in partial oxidation of ethanol to acetaldehyde by molecular oxygen (see diagram). The additional low-temperature peak (indicated by the arrow) probably corresponds to the specific participation of oxygen generated on Au/TiO2 surface under mild reaction conditions.
