Abstract
Hierarchical bismuth vanadate (BiVO
) nano-knitted hollow cages have been synthesized by simple hydrothermal method and characterized by scanning electron microscopy, x-ray diffraction, energy-dispersive x-ray spectrometer, Fourier transform infrared, UV-Vis, and Raman. The photodegradation efficiency of BiVO
nanocage for universally used methylene blue dye. The BiVO
hollow nanostructure demonstrated better photocatalytic competence in dye degradation as compared to the commercial TiO
powders (P25). The excellent dye degradation can be certified to the high crystallisation of monoclinic BiVO
and hollow nanostructure, which leads to high surface area and small bandgap energy of 2.44 eV.
