Photocatalytic degradation of tetracycline antibiotic by a novel Bi2Sn2O7/Bi2MoO6 S-scheme heterojunction: Performance, mechanism insight and toxicity assessment

Epitaxial Growth of Flower-Like MoS2 on One-Dimensional Nickel Titanate Nanofibers: A “Sweet Spot” for Efficient Photoreduction of Carbon Dioxide

“…Effect of heterostructure formation in the semiconductorbased photocatalysts has gained much interest. Semiconductorbased photo-catalysts showed dramatic reduction in the recombination rates with heterostructure formation which are widely applied in antibiotic removal 2022a), pharmaceutical wastewater treatment (Li et al, 2020b), and toxicity analysis applications (Li et al, 2022b;Wang et al, 2022). Therefore, a composite photocatalyst was required to effectively reduce recombination rates.…”

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.…”

Fabrication and characterization of a TiBs@MCN cable-like photocatalyst with high photocatalytic performance under visible light irradiation

“…6–8 Thus, developing highly durable and efficient photocatalysts with an effective and eco-friendly strategy is of great importance. 9–12…”

“…[6][7][8] Thus, developing highly durable and efficient photocatalysts with an effective and eco-friendly strategy is of great importance. [9][10][11][12] TiO 2 is a most widely used photocatalyst due to its nontoxicity, low cost, good oxidation capacity and photostability. 13 However, TiO 2 can only utilize a small portion of the solar spectrum (l o 400 nm, about 5% of sun energy) because of its wide bandgap (3.2 eV for the anatase phase and 3.0 eV for the rutile phase) and the rapid charge recombination of photoinduced electron-hole pairs, which limit its photocatalytic activity.…”
