The coupled effect of oxygen vacancies and Pt on the photoelectric response of tungsten trioxide films

Abstract

The coupled effect of Pt and oxygen vacancies makes Pt-H-WO3 show excellent sensitivity to formaldehyde in light or in the dark.

Synergistic Binary Fe–Co Nanocluster Supported on Defective Tungsten Oxide as Efficient Oxygen Reduction Electrocatalyst in Zinc‐Air Battery

“…[ 20 ] Compared with that of 3DOM Fe/Co@C‐WO 2− x (Ar), the oxidation state of W in 3DOM Fe/Co@NC‐WO 2− x is reduced, suggesting the formation of oxygen vacancy after the ammonia treatment. [ 21 ] The N 1s spectrum for 3DOM Fe/Co@NC‐WO 2− x was deconvoluted to four peaks located at 397.8, 398.4, 400.6, and 401.8 eV (Figure 4b ), which corresponds to metal‐N, pyridinic‐N, graphite‐N, and oxidized‐N, respectively. [ 22 ] The percentage for oxidized‐N, graphite‐N, pyridinic‐N, and metal‐N are 24.8%, 24.97%, 28.46%, and 21.77%, respectively (Table S2 , Supporting Information).…”

A cocatalyst-free Eosin Y-sensitized p-type of Co3O4 quantum dot for highly efficient and stable visible-light-driven water reduction and hydrogen production

“…17 In the space charge region, the energy band of the semiconductor shows bending due to the electric field. [17][18][19][20] Similarly, near the surface of semiconductor and water, energy band bending also occurs. 20 In a traditional dye-sensitized semiconductor system, an n-type semiconductor, such as TiO 2 , is usually used as a catalyst.…”

Maximizing the photo catalytic and photo response properties of multimodal plasmonic Ag/WO3−xheterostructure nanorods by variation of the Ag size
