Construction of coated Z-scheme Er3+:Y3Al5O12/Pd-CdS@BaTiO3 sonocatalyst composite for intensifying degradation of chlortetracycline hydrochloride in aqueous solution

Ultrasonic-assisted photocatalytic degradation of various organic contaminants using ZnO supported on a natural polymer of sporopollenin

“…The bandgap energy (E g ) values of ZnO and SP-ZnO were calculated using Tauc’s equation (Eq. (1) by depicting (αhν) 2 against hν [37] , [38] . where A, α, h , n, and ν represent a constant, the absorption coefficient, Planck’s constant, an index characterizing optical absorption, and light frequency, respectively.…”

“…Then, the adsorbed H 2 O and/or OH − can be oxidized by h + to produce •OH radicals. Moreover, other ROS, such as O 2 • − and HO 2 •, can be formed through the interaction of O 2 with CB electrons for pollutant degradation [29] , [38] .

A magnetically reusable Ce-MOF/GO/Fe3O4 composite for effective photocatalytic degradation of chlortetracycline

“…2,3 Chlortetracycline (CTC), as a kind of tetracycline antibiotic, is widely used for the disease treatment of animals and humans because of its easy preparation, low price, convenient use, and broad-spectrum antibacterial advantages. 4,5 However, only part of the CTC can be metabolized by animals and humans, and the unabsorbed residues will be released into the environment. 6 It is difficult to eliminate antibiotics via traditional wastewater treatment technology because of their stable chemical structure and resistance to biodegradation.…”

Luminescent porous metal–organic gels for efficient adsorption and sensitive detection of chlortetracycline hydrochloride assisted by smartphones and a test paper-based analytical device

“…2 Multifarious techniques have been explored for CTC removal, including adsorption, biological treatment, photocatalytic degradation and so on. [3][4][5][6] On the consideration of economic costs and operational complexities, adsorption has attracted tremendous attention from researchers. Thus, developing adsorbents with large adsorption amounts and recyclable capacities for guaranteeing the adsorption performance is conducive to CTC decontamination.…”
