Activity and mechanism of vanadium sulfide for organic contaminants oxidation with peroxymonosulfate

MnO2 Nanosheet Nets on Carbon Fiber as Fixed Catalysts for a Highly Efficient, Nonradical Fenton-like Process in Wastewater Refractory Pollutant Treatment

“…To reveal the main reactive oxygen species (ROS) in TC degradation, quenching experiments were carried out first by using different scavengers, i.e., methanol (EtOH) and tert -butyl alcohol (TBA) for •OH and SO 4 •– , p -benzoquinone ( p -BQ) for O 2 •– , furfuryl alcohol (FFA) for 1 O 2 , and l -histidine ( l -his) for PMS. − Interestingly, the addition of EtOH, TBA, or p-BQ showed no obvious restriction on TC removal (Figure a–c), which suggested that •OH, SO 4 •– , and O 2 •– had limited contribution to the TC degradation . However, the removal of TC was almost inhibited by the addition of FFA (Figure d).…”

“…•− had limited contribution to the TC degradation. 51 However, the removal of TC was almost inhibited by the addition of FFA (Figure 5d). Therefore, it could be speculated that 1 O 2 was the main ROS for oxidizing TC.…”

Extending 2D covalent organic frameworks by inserting anthracene for promoted white-light-mediated photocatalysis

“…45 In addition, most photocatalytic reactions utilize high-energy blue or green light sources. 46,47 Therefore, it is also essential to develop catalysts suitable for low-energy light sources, especially white light that approximates sunlight, potentially achieving efficient use of solar energy and advancing photocatalysis applications. 48 Combining the above concepts, we have innovatively engineered a novel anthracene-based COF (AND-TAPT), integrating anthracene units and triazine groups as electron donors/acceptors, respectively.…”
