“…The peak at 357 nm is from aromatic rings B, C, and D, comprising the extended chromophores. 53 40%WO 3 /g-C 3 N 4 can simultaneously destroy the rings B, C, D, and A, but the destructive effect on A is relatively weak under visible light. The slight shift in the location of the characteristic peak may be caused by the slight change in pH during the removal process.…”

“…TC is known to have two characteristic absorption peaks in the UV range located at 275 and 357 nm (Figure 9a). The shorter-wave peak at 275 nm is associated with the structure of aromatic ring A including enolic hydroxyl, amide and ketone groups, while its longer-wave peak at 357 nm belongs to the structure consisting of aromatic rings B, C and D [58]. Under irradiation without a catalyst, TC is stable and only ~6% of its molecules decompose within 8 h (Figure S4b).…”

Hydrosphere pollution by organic pollutants of different nature (persistent dyes, phenols, herbicides, antibiotics, etc.) is one of the urgent ecological problems facing humankind these days. The task of water purification from such pollutants can be effectively solved with the help of modern photocatalytic technologies. This article is devoted to the study of photocatalytic properties of composite catalysts based on ZnO modified with plasmonic Ag nanoparticles. All materials were obtained by laser synthesis in liquid and differed by their silver content and preparation conditions, such as additional laser irradiation and/or annealing of produced powders. The prepared ZnO-Ag powders were investigated by electron microscopy, X-ray diffraction and UV-Vis spectroscopy. Photocatalytic tests were carried out with well- known test molecules in water (persistent dye rhodamine B, phenol and common antibiotic tetracycline) using LED light sources with wavelengths of 375 and 410 nm. The introduction of small concentrations (up to 1%) of plasmonic Ag nanoparticles is shown to increase the efficiency of the ZnO photocatalyst by expanding its spectral range. Both the preparation conditions and material composition were optimized to obtain composite photocatalysts with the highest efficiency. Finally, the operation mechanisms of the material with different distribution of silver are discussed.

Photoelectrocatalytic technology (PEC) is an emerging green and sustainable technology for treating antibiotic wastewater. However, its effectiveness is limited by the recombination of photogenerated carriers. To address this issue, the Fenton reaction, an advanced oxidation process, can be coupled with PEC technology to enhance the oxidative degradation of antibiotic wastewater. This research involved creating a Zn0.5Ni0.5Fe2O4/silicon nanowires (SiNWs) Z‐type heterojunction through the spin coating technique, which was then utilized in the PEC coupled Fenton reaction to break down antibiotic wastewater. The inherent electric field and the voltage applied hastened the segregation of e− and h+ within the system. These advantages make the Zn0.5Ni0.5Fe2O4/SiNWs heterojunction highly efficient in removing various antibiotics, including tetracycline (TC), ciprofloxacin (CIP), amoxicillin (AMX), and levofloxacin (LVX). In particular, the Zn0.5Ni0.5Fe2O4/SiNWs heterojunction demonstrated an 82.21% degradation efficiency for TC, exhibiting a kinetic constant (k) of 0.02688 min−1, a rate 2.82 times (4.80 times) greater than that of SiNWs. Experimental findings reveal that Zn0.5Ni0.5Fe2O4/SiNWs exhibit superior light absorption properties and a reduced rate of photogenerated charge recombination. The doping of Zn0.5Ni0.5Fe2O4 effectively improves the catalytic performance of SiNWs. This research offers fresh insights into researching PEC‐coupled Fenton reaction methods for the degradation of antibiotics and paves the way for advancing the creation of more potent photoelectrochemical catalysts in the future.
