Interfacial architecture on quantum dots modified metal-organic frameworks: Charge transfer mechanism, antibiotic associated pollutants photodegradation and eco-toxicity prediction
The light harvesting and interfacial morphology of metal-organic framework (MOFs) based photocatalyst poses great significance for antibiotic resistance inhibition. Herein, the hybrid interface of the Z-scheme ZIF-8@CuFeS2 quantum dots (ZIF@CF QDs) was established, which exhibited superior photodegradation performance for antibiotic associated pollutants. Specifically, ZIF@CF QDs-Fe3O4 (ZIF@CF QDs-Fe) magnetic heterojunction achieved 90.27 % reduction of sulfamethoxazole (SMX) within 90 min (k=0.04496 min⁻¹), 5.99 lg inactivation of antibiotic resistant bacteria (ARB) and 4.57 lg of sul1 achieved within 6h. Notably, the built-in electric field of heterojunction was investigated via density functional theory (DFT) calculation, enhancing the charge migration during ZIF@CF QDs-Fe photoactivation. Furthermore, the radicals (·O₂⁻ and ·OH) photogeneration and redox cycles between metal ions (Zn2+, Fe2+/Fe3+, Cu2+) were strengthened in electronic path of ZIF@CF QDs-Fe. Besides, the repeatability and eco-toxicity inhibition guaranteed stable application in ecological photo-remediation. Hence, this study proposed an opportunity for nano-photocatalytic development, synergistically promising the light-conversion and wastewater purification in practical treatment.
期刊介绍:
Water Research, along with its open access companion journal Water Research X, serves as a platform for publishing original research papers covering various aspects of the science and technology related to the anthropogenic water cycle, water quality, and its management worldwide. The audience targeted by the journal comprises biologists, chemical engineers, chemists, civil engineers, environmental engineers, limnologists, and microbiologists. The scope of the journal include:
•Treatment processes for water and wastewaters (municipal, agricultural, industrial, and on-site treatment), including resource recovery and residuals management;
•Urban hydrology including sewer systems, stormwater management, and green infrastructure;
•Drinking water treatment and distribution;
•Potable and non-potable water reuse;
•Sanitation, public health, and risk assessment;
•Anaerobic digestion, solid and hazardous waste management, including source characterization and the effects and control of leachates and gaseous emissions;
•Contaminants (chemical, microbial, anthropogenic particles such as nanoparticles or microplastics) and related water quality sensing, monitoring, fate, and assessment;
•Anthropogenic impacts on inland, tidal, coastal and urban waters, focusing on surface and ground waters, and point and non-point sources of pollution;
•Environmental restoration, linked to surface water, groundwater and groundwater remediation;
•Analysis of the interfaces between sediments and water, and between water and atmosphere, focusing specifically on anthropogenic impacts;
•Mathematical modelling, systems analysis, machine learning, and beneficial use of big data related to the anthropogenic water cycle;
•Socio-economic, policy, and regulations studies.
