Abstract [en]

Hierarchical Bi2O3 spheres assembled from nanosheets with nanopore structure have been successfully synthesized by thermal decomposition of the precursor at 400 degrees C for 3 h in air, which was prepared using Bi (NO3)(3)center dot 5H(2)O and poly(vinylpyrrolidone) (PVP) by a microwave-assisted heating method in ethylene glycol (EG) at 150 degrees C for 10 min The morphology of Bi2O3 is similar to that of the precursor The products were characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectrometry (FT-IR), field-emission scanning electron microscopy (FE-SEM), thermogravimetric analysis (TG) and differential scanning calorimetric analysis (DSC) XRD pattern showed that the product had a high degree of crystallinity. FE-SEM micrograph indicated that hierarchical Bi2O3 spheres had sizes around 10 μm.
