Reusable piezocatalytic water disinfection activity of CVD-grown few-layer WS₂ on sapphire substrate

Abstract

Piezocatalysis of semiconductors is an arising technology that transforms mechanical stress into chemical energy to enhance reaction rate with piezo-generated free charge carriers. In the present work, CVD-grown few-layer WS2...

Solar/visible light photocatalytic dye degradation using BaTi1−xFexO3 ceramics

“…Looking to the emerging trends, organic pollutant degradation with visible light has become a topic of prime interest. Other materials, such as ZnO, WO 3 , Fe 2 O 3 , ZnS, CuO, WS 2 , and many ferroelectric materials such as BaTiO 3 , LiNbO 3 , and other BaTiO 3 ‐based materials, have also been well set down for their dye degradation abilities through photocatalysis process for applications like water cleaning 6,9–17 . However, their low photocatalytic efficiency resulted in the tailoring of these materials.…”

Many other methods, like bandgap tuning, doping of transition metals, and implantation of anions, are utilized to enhance photocatalytic activities.…”

Interface engineering of W2C/W2N co-catalyst on g-C3N4 nanosheets for boosted H2 evolution and 4-nitrophenol removal

“…8d. 46 The reaction rate constants were calculated and are listed in Table 3. The kinetics model is as follows:ln( C 0 / C ) = Kt where the initial and real-time concentrations of 4-NP are represented by C 0 and C , respectively, which were quantified based on the absorption values at 400 nm.…”

Organic pollutants removal by Quartz crystals

“…These catalytic effects are also known for killing bacteria and viruses. 12 Quartz in nature must actively participate in cleaning the environment through the application of natural mechanical vibrations driven by climate conditions. This could be a reason for believing in the healing effect from centuries ago.…”
