Synthesis of Nb2O5·nH2O nanoparticles by water-in-oil microemulsion
Source abstract
Abstract
Abstract Hydrous niobium oxide (Nb 2 O 5 · n H 2 O) nanoparticles had been successfully prepared by water-in-oil microemulsion. They were characterized by X-ray diffraction (XRD), thermal analysis (TG/DTG), Fourier transform infrared spectroscopy (FTIR), BET surface area measurement, transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The results showed that the nanoparticle was exactly Nb 2 O 5 · n H 2 O with spherical shape. Their BET surface area was 60 m 2 g −1 . XRD results showed that Nb 2 O 5 · n H 2 O nanoparticles with crystallite size in nanometer scale were formed. The crystallinity and crystallity size increased with increasing annealing temperature. TT-phase of Nb 2 O 5 was obtained when the sample is annealed at 550 °C.
