Hierarchical nanostructures of Ag3PO4 on TiO2 nanofibers with enhanced photocatalytic activity for the degradation of rhodamine B

In this work, a new hierarchical nanostructure of Ag3PO4/TiO2 was fabricated by a facile method. The Ag3PO4 nanocubes were uniformly grown on the surface of TiO2 nanofibers forming a heterostructure. The physical property, optical properties, crystalline and morphologic properties of the as-prepared nanomaterials were explored by characterized by X-ray diffraction, X-ray photoelectron spectroscopy, UV–Vis diffuse reflectance spectra, scanning electron microscopy, transmission electron microscopy and photoluminescence analyses. Compared with pure Ag3PO4 and TiO2 nanofibers, the Ag3PO4/TiO2 heterostructure exhibited highly efficient UV and visible light photocatalytic activity toward organic dye molecule rhodamine B (RhB).
