Heterojunction Architecture of N‐Doped WO₃ Nanobundles with Ce₂S₃ Nanodots Hybridized on a Carbon Textile Enables a Highly Efficient Flexible Photocatalyst

Abstract

The availability of robust, versatile and efficient photocatalysts has been a main bottleneck in practical applications of photocatalytic degradation of organic pollutants. Herein, N-WO 3 /Ce 2 S 3 nanotube bundles (NBs) were synthesized and successfully immobilized on a carbon textile, resulting in a flexible and conducting photocatalyst. Due to the large interfacial area between N-WO 3 and Ce 2 S 3 , the interwoven 3D carbon architecture and, more importantly, the establishment of a heterojunction between N-WO 3 and Ce 2 S 3 , the resultant photocatalyst exhibits excellent light absorption capacity and superior ability to separate photoinduced electron-hole pairs for the photocatalytic degradation of organic compounds in air and water media. Theoretical calculations confirm that the strong electronic interaction between N-WO 3 and Ce 2 S 3 could be beneficial to the enhancement of the charge carrier transfer dynamics of the as-prepared photocatalyst. This work provides a new protocol for constructing efficient flexible photocatalysts for application in environmental remediation.

Preparation Of ZnO/Co3O4 Hollow Microsphere By Pollen‐biological Template And Its Application In Photocatalytic Degradation

“…The electrons react with oxygen to form O 2 − , which reacts with water or protons to form O 2 • and HO 2 , and then continues to form OH − and •OH . These free radicals have a strong oxidizing power and can oxidize and decompose organic matter until they are completely mineralized into CO 2 and H 2 O …”

“…[55][56][57] These free radicals have a strong oxidizing power and can oxidize and decompose organic matter until they are completely mineralized into CO 2 and H 2 O. [58,59] Under the irradiation of visible light, the conduction band (CB) and the valence band (VB) of Co 3 [60,61] Therefore, the recombination of photogenerated charges can be suppressed under the irradiation of visible light. The two semiconductor materials can generate more electron-hole pairs, which are effectively separated and rapid transfered to the active sites, resulting in its enhanced activity compared with the single ZnO or Co 3 O 4 species.…”

“…Furthermore, the O 1s spectra (Figure 2d), revealing a singlet peak at 531.2 fitted into two main peaks at 531.6 and 532.4 eV, respectively. The first peak at 531.6 eV characteristic of oxygen ions in the metal oxide lattice, and the second peak at 532.4 eV can be related to the O−H bonding [6,36–38] …”

Optimized h‐BN/Sb2WO6 Interface Mediates an Efficient Charge Separation towards Enhanced Photocatalysis

“…The essential element of much talked about, environmental sustainability is the wastewater treatment. [1][2][3][4] Specifically, water pollution threatens the lives of two-thirds of the global population. [5,6] The major contributor to the water degradation are the dyes emanating from textile processing, leather tanning, paper production, food processing, and hair colorings.…”
