Abstract In this paper, hierarchical nanostructures of BiOBr/AgBr on electrospun carbon nanofibers (CNFs) were prepared by combination of electrospinning and carbonization. Compared with the smooth surface of CNFs, the rough surface with hierarchical nanostructures of BiOBr/AgBr can be obtained by adding the certain amount of BiOBr/AgBr precursors into the spinning solution. The as-prepared composite CNFs exhibited highly photocatalytic activities for degradation of rhodamine-B and reduction of p-nitrophenol under the visible-light irradiation and at room temperature. Furthermore, the as-prepared composite CNFs showed the favor separation, recovery, and cyclic utilization properties.
Introduction With the progress of society, the people’s living standard has been continuously improved. On the contrary, the negative effects on environment caused by environmental pollution and ecocide through human behavior have been got more and more attention. To solve this problems, degradation of toxic organic pollutants in wastewater or air has received considerable attention over recent years.[1–3] Recently, there are many approach to deal with pollutants, such as, biological treatment with enzyme[4,5] or microorganism,[6] physical treatment of wastewater with flocculating agent[7,8] and photocatalytic treatment with catalysts.[9–12] Because of the biological treatment is strict with its environment, especially with the occurrence of temperature, trivial change should disturb the enzyme or microorganism and make the number different from the reality.[13] Treated wastewater with flocculating agent has a highefficiency, but the flocculating agent cannot completely remove organic in wastewate
