CuS nanoflowers prepared by a polyol route and their photocatalytic property

摘要

CuS nanoflowers with a specific surface area of 18.8 m~2/g were prepared through a rapid polyol route at 140 ℃ for 90 min, and characterized by XRD, SEM, UV-vis spectrum and BET surface area. The formation of CuS nanoflowers is proposed to experience an aggregation and growth process. The photocatalytic activity of CuS nanoflowers was investigated by decomposing Rhodamine B at atmosphere and the result shows that the photocatalytic activity under halogen lamp irradiation is comparable to that of Degussa P25 TiO_2.
