Activation of oxygen on gold-alumina catalysts: in situ high-energy resolution

Activation of oxygen on gold-alumina catalysts: in situ high-energy resolution
Activation of oxygen on gold-alumina catalysts: in situ high-energy resolution
Gold catalysis has received considerable attention in recent years. Particles of gold that are unsupported or supported on oxidic carriers have been reported to be very active in various oxidation reactions. Examples are the oxidation of CO to CO2, water-gas shift reaction (CO + H2O ? 2CO2 + H2) and oxidation of hydrocarbons. The origin of the high catalytic activity of gold catalysts has been strongly debated and various models have been presented. The major question to be answered is how the oxygen molecule is activated.

Abstract

Gold catalysis has received considerable attention in recent years. Particles of gold that are unsupported or supported on oxidic carriers have been reported to be very active in various oxidation reactions. Examples are the oxidation of CO to CO2, water-gas shift reaction (CO + H2O ? 2CO2 + H2) and oxidation of hydrocarbons. The origin of the high catalytic activity of gold catalysts has been strongly debated and various models have been presented. The major question to be answered is how the oxygen molecule is activated.
