Photocatalytic activity of flower-like carbon/Ag3PO4 composite microspheres for pollutant degradation

The photosensitivity of Ag3PO4 seriously affects the photocatalytic activity, thus it is of great importance for settling the harsh drawback. In this work, 3D flower-like carbon microspheres (FCMs) prepared have been applied to modify Ag3PO4 to improve the structural stability and the photocatalytic property. Nanoscale Ag3PO4 with 20-30 nm can be uniformly distributed on the surface of modified-FCMs. Compared with Ag3PO4 and FCM/Ag3PO4, modified-FCM/Ag3PO4 shows favourable reusability, adsorptive ability and enhanced photocatalytic performance for the degradation of chloramphenicol. In addition, h(+) and center dot O2- radicals play a major role in the photocatalytic process. (C) 2016 Elsevier B.V. All rights reserved.
