Fabrication and characterization of WO3 flocky microspheres induced by ethanol

Photocatalysis of WO3 Nanoplates Synthesized by Conventional‐Hydrothermal and Microwave‐Hydrothermal Methods and of Commercial WO3 Nanorods

“…For ℎ] < , the absorption curves are different from linearity, caused by charged transition relating to defects. In the present research, direct energy gaps of the products synthesized by the C-H at 120, 160, and 200 ∘ C for 12 h were determined to be 2.60, 2.96, and 3.22 eV, respectively [2,29,30]. In addition, the direct band gap of commercial WO 3 was determined to be 2.63 eV [8].…”

Hydrothermal synthesis of WO3 films on the TiO2 substrates and their photochromic properties

“…What's more, S3 shows larger exposed surface, which is of great benefit to absorption of excitation light, thus resulting in increase of protons and photo-generated electron-hole pairs. As a result, S3 reveals the best photochromic properties [24,25].…”

“…According to the model of double insertion-extraction of ions and electrons, the diffuse rates of protons and the amount of the photoinduced electrons-hole pairs are of great benefit to the photochromic progress [24]. The improved crystallinity of S3 is conducive to the migration of the photoinduced electrons-hole pairs [25]. So, it exhibits enhanced photochromic properties.…”

DFT investigation on CO sensing characteristics of hexagonal and orthorhombic WO3 nanostructures

“…Oxygen vacancies play a vital role in gas sensing characteristics [17,18]. So far, WO 3 with various sizes and morphologies has been reported such as nanosheets [19], nanoparticles [20], nanowires [21], microspheres [22] and nanotubes. In recent days, researchers have been trying to achieve the surface-controlled synthesis of WO 3 [23][24][25].…”
