Preparation of Co-Al mixed oxide supported gold catalysts and their catalytic activity for N2O decomposition
钴铝复合氧化物负载金催化剂的制备及催化分解N2O

Au/Co-Al catalysts were prepared by using the ion-exchanged and co-precipitation methods,and their activities for the catalytic decomposition of N2O were tested.BET,XRD,and H2-TPR techniques were used to characterize the catalysts.The results show that the activity of Au/Co-Al catalyst prepared by using ion-exchanged method is higher than that using co-precipitation method.For the catalysts prepared by ion-exchanged method,the effects of preparation parameters,such as Au loading,pretreatment of HAuCl4 solut...
