Self-sensitization of tetracycline degradation with simulated solar light catalyzed by ZnO@montmorillonite

Microwave-assisted synthesis of a Z-scheme heterojunction Ag/AgBr@BiOBr/Bi2O3 photocatalyst for efficient organic pollutant degradation under visible light

“…The TCH blank test indicated chemical stability with a slight decrease (7.8%) in concentration for 60 min due to the TCH oxidation process by positive holes generated from the photoexcitation of the TCH molecule under solar light. 38…”

“…The TCH blank test indicated chemical stability with a slight decrease (7.8%) in concentration for 60 min due to the TCH oxidation process by positive holes generated from the photoexcitation of the TCH molecule under solar light. 38 Fig. 7c and d present the rate constants (k) for the degradation reaction of TCH in the presence of different photocatalysts, which increased in the following order: AgBr (k = 0.007 min −1 ) < BiOBr (k = 0.015 min −1 ) < BiOBr/Bi 2 O 3 (k = 0.024 min −1 ) < Ag/AgBr@BiOBr/Bi 2 O 3 (k = 0.034 min −1 ).…”

Synthesis of a plasmonic AgCl and oxygen-rich Bi24O31Cl10 composite heterogeneous catalyst for enhanced degradation of tetracycline and 2,4-dichlorophenoxy acetic acid

“…TC is characterised by a yellow colour which has a major absorption range in wavelength 300–430 nm (ref. 38 ) while 2,4-D is colourless. This enables TC molecules to be sensitised by visible light and be easily adsorbed on the surface of the photocatalysts thereby enhancing photodegradation due to the closeness of the adsorbed contaminants with that of the reactive sites.…”

Antibiotics Contaminated Irrigation Water: An Overview on Its Impact on Edible Crops and Visible Light Active Titania as Potential Photocatalysts for Irrigation Water Treatment

“…In addition to enhanced visible light activity, the practical and large scale application of Titania would necessitate catalyst stability and recyclability. Accordingly, many studies have investigated the immobilization of doped-TiO 2 on various polymeric Mahdavi et al, 2019), carbonaceous and ceramic supports such as polyphenylenediamine (POPD) (Yu et al, 2014), graphene, reduced graphene oxide (rGO) (Cao et al, 2016;Huo et al, 2016;Wang W. et al, 2017;Zhang F. J. et al, 2017;Tang et al, 2018;Jamali Alyani et al, 2019;Tabatabai-Yazdi et al, 2020), mesoporous carbon (Fang et al, 2019), MOFs (He et al, 2018;Yuan et al, 2021), zeolites (Saadati et al, 2016b;Liu M. et al, 2019), and silica (Yu et al, 2014;Chen and Liu, 2016;Chen and Liu, 2017;Zyoud et al, 2017;Li J. et al, 2019;Wang et al, 2019). These systems are prepared as composites , and the solid support provides three primary advantages: 1) high surface area which increases tetracycline adsorption, 2) enhanced light absorption and electron entrapment which enhances photocatalytic activity, and 3) reduced sintering and aggregation which leads to superior stability.…”
