Hierarchical structures constructed by BiOX (X = Cl, I) nanosheets on CNTs/carbon composite fibers for improved photocatalytic degradation of methyl orange
Source abstract
Abstract
A hierarchical structure (CNTs/CFs-NSs) of BiOX (X = Cl, I) nanosheets (NSs) on carbon fibers (CFs) embedded with aligned carbon nanotubes (CNTs) with improved photocatalytic activities has been developed on a large scale. In the CNTs/CFs obtained by centrifugal spinning, CNTs align along the axis of the CFs, form π–π stacking interactions with CFs and strength the electrical conductivity of CFs, which favors the electron collection and transportation. Cross-flake BiOX NSs were uniformly grown on the surface of CNTs/CFs through a successive ionic layer adsorption and reaction process. The as-prepared BiOX NSs are less than 20 nm in thickness with dominant reactive (001) facets that are almost fully exposed, promoting the photocatalytic properties. The hierarchical CNTs/CFs-NSs show 3- and 2-fold improved photocatalytic activities for degradation of methyl orange for BiOCl and BiOI compared to corresponding neat NSs, respectively, given the synergistic effects of CNTs/CFs and NSs. Moreover, these novel hierarchical structures with stable performance enhance the recycled ability for the photocatalyst.
