Photocatalytic degradation of ciprofloxacin in freshwater aquaculture wastewater by a CNBN membrane: mechanism, antibacterial activity, and cyclability

“…According to the FED, ˙OH preferred to attack atoms with high FED HOMO 2 + FED LUMO 2 values. 72 Thereby, O (20) was susceptible to the influence of ˙OH and broke away from CIP to form P1. Further degradation occurred along pathway I, 73 where the carboxyl group of P1 was lost to form P3 which suffered defluorination to form P4.…”

“…[12][13][14] However, BN has limitations that include a wide band gap and low light energy utilization efficiency, which should be modified for practical applications. To overcome these shortcomings, researchers have pioneered many advanced photocatalyst optimization techniques, which include morphological control, 15 composite materials, 16 MXene material modification, 17 novel graphene modification, 18,19 functionalization of photocatalysts, 20 organic polymer modifications, 21 etc.…”

Turn Hazardous Endosulfan into S-Doped Alkynyl Carbon Material for Energy Storage and Hg(II) Adsorption via a Green Mechanochemical Process

“…In addition, ACMs can be also synthesized through introducing alkynyl groups into relevant materials under mechanochemical activation of CaC 2 . 25 possess a stable skeleton structure, rich alkynyl groups, and electron-rich and soft-base sites, thus showing great potential in applications in many fields such as energy, environment, catalysis, and so forth. 26 On this basis, a solvent-free mechanochemical strategy was proposed, whereby endosulfan was reacted efficiently with CaC 2 , accompanying its degradation and in situ synthesis of S-doped ACM (SACM).…”

“…Recently, mechanochemistry, as an active chemical technology, exhibits unique features and compelling advantages in solid-state chemical reactions. − It has been successfully used for the solid reactions of CaC 2 with many polyhalohydrocarbons. − In these processes, CaC 2 is mechanically activated and reacted with polyhalohydrocarbons through nucleophilic substitution of the chlorines by alkynyl anions, forming unique alkynyl carbon materials (ACMs). In addition, ACMs can be also synthesized through introducing alkynyl groups into relevant materials under mechanochemical activation of CaC 2 . Notably, the as-prepared ACMs generally possess a stable skeleton structure, rich alkynyl groups, and electron-rich and soft-base sites, thus showing great potential in applications in many fields such as energy, environment, catalysis, and so forth .…”
