【Abstract】 The title nano-powder catalysts were prepared by precipitation under ultrasonic radiation.The composition, structure, particle size and activity of catalysts for H 2O 2 decomposition were investigated by XRD、IR and TEM. The results show that it could improve the properties of catalysts while ultrasonic radiation was introduced into the process of oxides catalysts prepared by precipitation. and which was discussed in this paper.更多还原
