Photocatalytic degradation of antibiotics using a novel Ag/Ag2S/Bi2MoO6 plasmonic p-n heterojunction photocatalyst: Mineralization activity, degradation pathways and boosted charge separation mechanism

Ag Decoration and SnO2 Coupling Modified Anatase/Rutile Mixed Crystal TiO2 Composite Photocatalyst for Enhancement of Photocatalytic Degradation towards Tetracycline Hydrochloride

“…Antibiotics have been widely used in our daily life for decades. If they are not treated as non-toxic, these antibiotics will eventually enter the water and soil, threatening human health [ 1 , 2 , 3 , 4 ]. Employing photocatalytic technology to degrade antibiotics is a green and efficient route, which shows broad application prospects.…”

Facile fabrication of electrospun g-C3N4/Bi12O17Cl2/poly(acrylonitrile-co-maleic acid) heterojunction nanofibers for boosting visible-light catalytic ofloxacin degradation

“…Antibiotics are a significant class of emerging organic contaminants (EOCs), and have been widely detected in various water samples from tap water, surface water, groundwater, to waste water, 16–18 and therefore, many approaches, including adsorption methods, 19,20 ozonation-based treatments, 21 microalgae-based technology, 22 electrochemical methods 23 and especially photocatalytic degradation, 24–40 have been developed to remove antibiotics from water samples. Among these approaches, the photocatalytic degradation method has become the preferred approach for antibiotics removal with high degradation efficiency, and thus some novel photocatalysts such as WO 3 /Bi 2 MoO 6 , 25 Bi 2 WO 6 /Ta 3 N 5 , 26 Ag/Ag 2 S/Bi 2 MoO 6 , 27 Bi 2 Sn 2 O 7 /Bi 2 MoO 6 , 29 tetra (4-carboxyphenyl)porphyrin/Bi 2 MoO 6 , 30 MoO 3 /Ag/C 3 N 4 , 31 UiO-67/CdS/rGO, 32 Bi 2 MoO 6 -rGO-TiO 2 , 33 BiVO 4 /g-C 3 N 4 /NiFe 2 O 4 , 34 Bi 2 WO 6 , 35 ZnO/Bi 2 MoO 6 , 36 g-C 3 N 4 /NH 2 -MIL-88B(Fe), 37 UiO-66/wood, 38 and BiOCl/Cu-doped Bi 2 S 3 composites 39 have been fabricated and applied for antibiotics degradation. However, these reported photocatalysts were powders, which limited their practical applications because of at least two obvious problems: (1) the recovery and recycling of the powdered photocatalysts in the degradation process and (2) the loss of photocatalytic activity of the photocatalyst.…”
