Abstract

AbstractNiobium pentoxide (Nb2O5) is a polymorphic ceramic with semiconductor characteristics applied in various fields of study. In this work, the Nb2O5 synthesis by the spray pyrolysis route was compared to the hydrothermal technique. The obtained materials were characterized by N2 physisorption (BET‐N2), average particle size distribution by dynamic light scattering (DLS), X‐ray diffractometry (XRD), transmission electron microscopy (TEM), and X‐ray fluorescence (XRF) spectroscopy. The material synthesized by the spray pyrolysis technique presented high specific area and pore volume, high crystallinity, homogeneity, and nanometric particles, thus representing a potential technique for the Nb2O5 synthesis.
