Title
Selectivity control of ethanol gas-phase oxidation over nanoporous gold
Abstract

The gas-phase oxidation of ethanol over unsupported nanoporous gold was studied using catalyst with Ag content of 26.56% and 0.72%. Influence of Ag content in the catalyst, partial pressure of oxygen and temperature are analyzed. Under optimal conditions, selectivity toward acetaldehyde, ethyl acetate and acetic acid achieved 90%, 85% and 48% respectively.

Graphical abstractThe gas-phase oxidation of ethanol over unsupported nanoporous gold was studied. Influence of Ag content in the catalyst, partial pressure of oxygen and temperature are analyzed. Optimal conditions for high selectivity toward acetaldehyde, ethyl acetate and acetic acid are achieved accordingly.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Bimetallic system is adopted to enhance the activity of nanoporous gold(NPG). ► Selectivity controlled to produce three partial oxidation products of ethanol. ► Solvent free system at ambient pressure with O2:N2 ratio equal to that in the air.
