Preparation of Fe-Ni-Mn/Al2O3 catalyst by ultrasonic irradiation impregnation method and its property investigation
超声辐射浸渍法制备Fe-Ni-Mn/Al2O3催化剂及性能研究

In this study,with Al2O3 as the carrier,Fe-Ni-Mn/ Al2O3 catalyst was prepared with ultrasonic irradiation impregnation method and conventional impregnation method separately.The physicochemical properties and microstructure of the catalyst were examined by means of BET,XRD and SEM.With simulated wastewater containing Acid Green B,the catalytic performance of the prepared catalyst was examined.It was found that the pH value of impregnation solution and calcination temperature had significant effect on the properties of this catalyst.Compared with catalyst prepared with conventional impregnation method,Fe-Ni-Mn/Al2O3 catalyst prepared with ultrasonic irradiation impregnation method had higher catalytic activity in the decolorization process of Acid Green B.
