Abstract An amorphous Au25Zr75 alloy showed a high catalytic activity for hydrogenation of carbon monoxide. Thus, the rate of methanation was 2.3 μmol s−1 g−1 under 6.0 MPa at 523 K, being much higher than that over Au/ZrO2 or ZrO2. It was found that the alloy was oxidized into metallic gold and ZrO2 under the reaction conditions.
