摘要

<正>Ternary catalysts,namely CuO-CoOx-CeO_2,are prepared by coprecipitation with different p H and characterized by techniques such as N2 adsorption/desorption,XRD,TPR,TEM and XPS.The results show that p H plays a crucial role in determining the physicochemical properties such as surface area,particle sizes and valence states of the elements on the surface of the catalysts.It can also be found that suitable p H values may facilitate the formation of Cu~+ and the redox recycle of
