WO3 ElectoPun Nanofibers für NO2-Gaserfassungen

Electrospun functionalized nano-materials for ultra ...

The TiO2-V2O5-WO3 with high catalyst contents ( V2O5-WO3 above % in weight) can easily give full NOx conversion ( 100 % conversion of NOx into N2), especially at the high temperatures above 300 °C. In this work, the amount of samples used at each test is only 20 mg for a flow of 6 L/h. Such small amount of catalyst leads to conversion degree that rarely exceeds 90% even at the ...

[PDF] The Influence of Temperature and Visible Light ...

Aim of this work is to compare the electrical responses to 100–400 ppb NO2 gas concentrations of WO3 electrospun nanofibers both activated by thermal (in the temperature range 25–100 °C) and/or visible light at different wavelengths (Red λ = 670 nm, Green λ = 550 nm, and Purple-Blue λ = 430 nm). WO3 nanofibers were prepared by mixing a W-O sol-gel transparent solution with a polymeric ...

SnO2 Nanoribbons as NO2 Sensors: Insights from First ...

28/06/2003· SnO2 nanoribbons with exposed (1 0 1̄) and (0 1 0) surfaces have recently been demonstrated to be highly effective NO2 sensors even at room temperature. The sensing mechanism is examined here through first principles density functional theory (DFT) calculations. We show that the most stable adsorbed species involve an unexpected NO3 group doubly bonded to Sn centers.
