Photocatalytic radical species: An overview of how they are generated, detected, and measured

Fabrication of ternary metal oxide (ZnO:NiO:CuO) nanocomposite heterojunctions for enhanced photocatalytic and antibacterial applications

“…In order to propose suitable mechanism of photodegradation and presence of main oxygen species involved in this process, radical scavenging/ inhibition tests were carried out. 67,68 Four radical scavengers were used in batch experiments. Ethylenediaminetetraacetic acid (EDTA), p-benzoquinone (p-BQ), isopropanol (IPA) and Lascorbic acid (L-AA) were used to scavenge holes (h + ), super oxide anion radical (O 2 c − ), hydroxyl radical (OHc) And hydrogen peroxide (H 2 O 2 ), respectively.…”

An electron-donating system composed of a CIDS@CFO@F0C0 catalyst for the sustainable generation of free radicals to inactivate pathogens

“…12 However, some of these require extra energy such as light or electricity to excite electrons to trigger the oxidation-reduction reactions; while others need the assistance of highly active oxidants to accelerate the reactions and ease the formation of radicals. 13,14 Consequently, the cost will be greatly increased, which will significantly impede their practical application. 15 In recent years, catalyzing O 2 / H 2 O by strong reductants to obtain ROS has attracted extensive attention.…”
