Ordered mesoporous WO3/ZnO nanocomposites with isotype heterojunctions for sensitive detection of NO2

The Removal of Formaldehyde via Visible Photocatalysis Using the Black TiO2 Nanoparticles with Mesoporous

“…BET surface area of W‐TiO 2 and B‐TiO 2 are 104.50, 175.34 m 2 /g respectively. Both of the samples have a hysteresis loop at relative medium pressure, which reveals the existence of mesoporous in the samples . It is also confirmed by the BJH pore size distributions curves (Figure b).…”

N,Cu-CD-Decorated Mesoporous WO3 for Enhanced Photocatalysis Under UV–Vis–NIR Light Irradiation

“…In the survey scan of the XPS spectra of the N,Cu-CDs/ m-WO 3 -0.8 nanocomposite ( Supplementary Figure S1), the presence of C, N, O, W, and Cu further verified that the N,Cu-CDs were successfully combined with the m-WO 3 . In the high-resolution W 4f spectra ( Figure 4B), the W of pure m-WO 3 existed in four different states: W 4f 5/2 of W 6+ , W 4f 7/2 of W 6+ , W 4f 5/2 of W 5+ , and W 4f 7/2 of W 5+ (at 37.80, 35.64, 36.80, and 34.50 eV, respectively), which suggested that the m-WO 3 contained rich oxygen vacancies (Sun et al, 2019). In the O 1s spectra ( Figure 4C), the O 1s peaks in the pure m-WO 3 were divided into two peaks at 530.36 and 531.25 eV, which were ascribed to the lattice oxygen (W-O) and the adsorbed oxygen, respectively (Zhu et al, 2017).…”

Gasochromic WO3 Nanostructures for the Detection of Hydrogen Gas: An Overview

“…Further, it is transparent to visible and infrared light. Therefore, it has been used in different applications including smart windows [21], photocatalysts [22], solar cells [23], humidity sensors [24], and gas sensors [25]. Moreover, due to its excellent coloration efficiency [26], WO3 is the most used chromogenic material in photochromic, electrochromic, and gasochromic applications [27].…”
