The utilization of titanium dioxide (TiO2) as a photocatalyst for the treatment wastewater has attracted significant attention in environmental field. Herein, we prepared an NH2-MIL-125-derived N-doped TiO2@C Visible Light Catalyst through situ calcination method. nitrogen element organic connector was released calcination, simultaneously doping into sample, thereby enhancing its spectral response to cover visible region. as-prepared catalyst exhibited preserved cage structure even after alleviating optical shielding effect and further augmenting photocatalytic performance by increasing reaction sites between pollutants. time TiO2@C-450 °C optimized achieve balance TiO2 content level, ensuring efficient degradation rates basic fuchsin (99.7%), Rhodamine B (89.9%) tetracycline hydrochloride (93%) within 90 min. Thus, this study presents feasible strategy pollutants under light.

Facile Synthesis to Porous TiO2 Nanostructures at Low Temperature for Efficient Visible-Light Degradation of Tetracycline

Nanomaterials, Journal Year: 2024, Volume and Issue: 14(11), P. 943 - 943

Published: May 27, 2024

In this study, nanoporous TiO2 with hierarchical micro/nanostructures was synthesized on a large scale by facile one-step solvothermal method at low temperature. A series of characterizations performed and carried out the as-prepared photocatalysts, which were applied to degradation antibiotic tetracycline (TC). The results demonstrated that obtained temperature 100 °C had spherical morphology high crystallinity relatively specific surface area, composed number nanospheres. exhibited excellent photocatalytic activity for TC under simulated sunlight. rate close 100% after 30 min UV light irradiation, reached 79% only 60 visible much better than photodegradation performance commercial (only 29%). Moreover, possible intermediates formed during explored density functional theory calculations HPLC-MS spectra. Furthermore, two routes proposed, provided experimental theoretical support TC. we provide new approach micro/nanostructure TiO2, can be in industrial manufacturing fields.

Abstract In this work, novel ternary composite ZIF‐67/Ag NPs/NaYF 4 :Yb,Er is synthesized by solvothermal method. The photocatalytic activity of the evaluated sulfadiazine (SDZ) degradation under simulated sunlight. High elimination efficiency 95.4% in 180 min with good reusability and stability. active species (h + , ·O 2 − ·OH) are identified. attack sites process SDZ deeply investigated based on theoretical calculation liquid chromatography‐mass spectrometry analysis. upconversion mechanism study shows that favorable effectiveness attributed to full utilization sunlight through energy transfer fluorescence resonance transfer. Additionally, endowed outstanding light‐absorbing qualities effective photogenerated electron–hole pair separation thanks localized surface plasmon effect Ag nanoparticles. This work can motivate further design photocatalysts luminescence performance, which applied removal sulphonamide antibiotics environment.
