Investigation of acid sites on V2O5/Nb2O5 catalysts by FTIR

, 1995
In this study the V2O5/Nb2O5 catalysts were prepared using grafting and impregnation techniques. Both the V2O5/Nb2O5 prepared catalysts and the adsorption of pyridine on V2O5/Nb2O5 have been studied with FTIR spectroscopy.

Multi‐Objective Inverse Design of a Dual‐Narrowband Thermal Emitter for Optical Gas Sensing

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
A lithography‐free, wafer‐scale dual‐narrowband thermal emitter is developed using a multi‐objective inverse design framework. It comprises an aperiodic Si/SiO2 dielectric multilayer deposited on a TiN refractory conductive ceramic film. Its dual emission peaks match characteristic absorption bands of CH4 and NO2 and enhance responses to both gases ...

Влияние кристаллической структуры на ширину запрещенной зоны Nb2O5

, 2014
В работе проводилась полная оптимизация кристаллической структуры с последующим расчетом зонных спектров различных фаз Nb2O5. Для этого был применен первопринципный метод псевдопотенциала с базисным набором плоских волн (пакета VASP).

Hydrothermal growth and optical properties of Nb2O5 nanorod arrays

, 2014
Nb2O5 nanorod arrays were grown on Nb foil through an in situ hydrothermal treatment process using NH4F as the mineralizing agent and H2O2 as the oxidant. The as-prepared Nb2O5 nanorod arrays were well crystallized with a hexagonal structure and a c-axis

Nb2O5 ve Nb2O5 tabanlı ince filmlerin karakterizasyonu ve güneş pili üretimi

, 2021
In this thesis, as an alternative materials to titanium oxide, Nb2O5 having wide band gap (~3.2 eV), photoanodes were obtained. The characterization of these materials was carried out. Photoelectrodes made of sol-gel method the thin film (a few microns thick) and as well as films produce from paste application, with the of 10-15 micron thickness. Films
