Fabrication of CdS/titanium-oxo-cluster nanocomposites based on a Ti32 framework with enhanced photocatalytic activity for tetracycline hydrochloride degradation under visible light

Transformation of novel TiOF2 nanoparticles to cluster TiO2-{001/101} and its degradation of tetracycline hydrochloride under simulated sunlight

“…Besides, these uniform and small pore size mesopores are conducive to the absorption of light and multiple reections inside the material and provide an effective transmission path for photogenerated carriers. 3 Fig. 5a shows the FT-IR spectra of photocatalysts prepared at different hydrothermal reaction times.…”

“…2 Drinking water containing TCH for a long time will cause a series of diseases such as bacterial disorders, gastrointestinal reactions and mycoplasma pneumonia, and affect the growth of teeth and bones. [3][4][5] In recent years, some methods have been used to treat TCH wastewater, such as microbial degradation, 6,7 adsorption, 8,9 electrochemical method, 10 membrane separation method, 11,12 photocatalytic degradation. [13][14][15][16] Among these methods, photocatalytic water purication technology is considered to be the most promising water treatment technology due to its economic, efficient and clean environment.…”

Recent advances in the roles of minerals for enhanced microbial extracellular electron transfer

“…Timely microbial degradation of byproducts effectively circumvents any adverse effects imposed by unfavorable oxidation conditions and interferences with microbial metabolic processes. Recent research reports successful degradation of bio-recalcitrant pollutants, including tetracycline hydrochloride, reactive dyes, phenazopyridine and nitrofurazone, by ICPB reactors configured with specific mineral analogues or their modified substitutes [153][154][155][156]. Overall, amendment of ICPB systems with specific mineral substituents offers operational efficiencies and flexibility for application in pollutant control and bioremediation strategies.…”

Cadmium sulfide nanoparticles-assisted intimate coupling of microbial and photoelectrochemical processes: Mechanisms and environmental applications

“…Thus, complete removal of bio-refractory organic pollutants in the presence of CdS NPs is ascribed to the synergistic effects of adsorption, photocatalysis and biodegradation resulting from intimate coupling of photocatalysis and microbial degradation. Several examples of intimately coupled degradation processes for mineralization of biorefractory organic pollutants include tetracycline hydrochloride (Zhu et al, 2019b), reactive dyes (Cui et al, 2018), phenazopyridine (Zyoud et al, 2010) and nitrofurazone (Hou et al, 2020). Intimate coupling of degradation processes, such as these, holds great potential for enhanced wastewater treatment of industrial pollutants.…”
