Abstract

Abstract : NCC/POM/ACF composite material was successfully fabricated, and displays excellent photocatalytic activity in visible light. Abstract : To enhance the photocatalytic properties of coordination complex modified polyoxometalates (CC/POMs ) in the visible light region, its nanobelts (CC/POMNBs ) were loaded on activated carbon fiber (ACF ) through a simple colloidal blending process. The resulting coordination complex modified polyoxometalate nanobelts loaded activated carbon fiber composite materials (CC/POMNBs/ACF ) exhibited dramatic photocatalytic activity for the degradation of rhodamine B (RhB) under visible light irradiation. Optical and electrochemical methods illustrated the enhanced photocatalytic activity ofCC/POMNBs/ACF, which originates from the high separation efficiency of the photogenerated electrons and holes on the interface of theCC/POMNBs andACF, which results from the synergistic effects between them. In the composite material, the role ofACF could be described as a photosensitizer and a good electron transporter. Furthermore, the influence of the mass ratio between theCC/POMNBs andACF on the photocatalytic performance of the resulting composite material was discussed, and an ideal value to obtain highly efficient photocatalysts was obtained. The results suggested that the loading ofCC/POMNBs on the surface ofACF would be a feasible strategy to enhance their photocatalytic activity.
