Niobium pentoxide is the inorganic compound with the formula Nb 2 O 5. A colorless, insoluble, and fairly unreactive solid, it is the most widespread precursor for other compounds and materials containing niobium.

The 1%Fe-Nb2O5 sample showed the best photocatalytic discoloration result, achieving 100% discoloration of RhB within 60 minutes.

There are a spread of Nb–O bond distances ranging from 1.88–2.31 Å. In the eleventh Nb5+ site, Nb5+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing NbO6 octahedra.

Apr 10, 2023 · In this work, a thermal-reduction promoted phase-transition strategy is utilized to construct high-density FLP sites on Nb 2 O 5 composed of low-valence Nb (LA site) and Nb-OH (LB site) that are...

Nb2O5 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Nb5+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Nb–O bond distances ranging from 1.90–2.43 Å. There are three inequivalent O2- sites.

Nov 13, 2019 · The spectrum of Nb 2 O 5 ·nH 2 O exhibits a broad band due to the vibration of Nb−O bonds, whereas those of Nb 2 O 5-NP and Nb 2 O 5-NS show two bands in the same region, indicative of two...

Aug 1, 2021 · Using the first-principles density functional theory, we have studied the structural, excitonic and electronic properties of Nb2 O 5 with five different crystal structures. In this paper, the structural characteristics of monoclinic, orthorhombic …

Niobium pentoxide (Nb 2 O 5), as an important dielectric and semiconductor material, has numerous crystal polymorphs, higher chemical stability than water and oxygen, and a higher melt point than most metal oxides.

Nb2O5 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Nb5+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing NbO6 octahedra.
