Carbon dots (CDs), as a revolutionary nanomaterial, exhibit unique advantages in terms of wastewater treatment, offering new opportunities for the development water treatment technologies due to their simple synthesis methods, excellent biocompatibility, tunable optical properties, and favorable environmental performance. This review systematically discusses structural characteristics, application progress carbon highlighting several key findings. (1) Excellent adsorption performance: CDs can effectively remove heavy metal ions, dyes, organic pollutants from water. (2) Outstanding photocatalytic Some carbon-dot-enhanced systems efficiently under visible light. (3) Exceptional selective detection ability: are capable highly sensitive metals water, with limits reaching nanomolar level. (4) Enhanced membrane separation The high flux selectivity carbon-dot-modified membranes make them suitable efficient quality separation. (5) Enhancement biological treatment: In systems, significantly improve microbial activity electron transfer efficiency enhance degradation processes. (6) Sustainable utilization waste raw material regeneration conducive reducing cost preparation CDs. These findings indicate that have broad potential treatment. Furthermore, this looks ahead future directions proposing innovations catalytic performance enhancement, control, practical applications, aiming provide important references guidance research industrial

Progress of research on aroma absorption mechanism and aroma fixation pathway of jasmine green tea

Journal of the Science of Food and Agriculture, Год журнала: 2024, Номер unknown

Опубликована: Июнь 15, 2024

Abstract This overview summarizes the latest research progress on aroma absorption mechanism and fixation pathway of jasmine green tea, discusses in depth release flowers, as well components tea process scenting, to provide a theoretical basis for improvement quality innovation processing technology. It was found that is mainly associated with both physical chemical adsorption, involves phenylpropanoid/benzoin biosynthetic pathway, β‐glycosidase enzymes interpreting putative glycosidic groups, heat shock proteins (HSPs) molecular chaperones prevent stress damage postharvest flowers due high temperatures promote components, so forth. The preparation aroma‐protein nano‐complexes, microcapsules, spraying polymeric substances – β‐cyclodextrin are three examples aroma‐fixing pathways. also problems future development trends current proposes method loading benzyl acetate, main component jasmine, through konjac glucomannan (KGM)‐based gel solve problem volatile difficult‐to‐fix aroma, which provides reference sustainable industry. © 2024 Society Chemical Industry.

Photocatalyst for Antibiotics Degradation by In Situ Growth of Direct Z-Type Bi₂S₃/Bi₄Ti₃O₁₂ Heterojunction

Inorganic Chemistry, Год журнала: 2024, Номер 63(46), С. 22088 - 22100

Опубликована: Ноя. 1, 2024

Effective removal of antibiotics from aqueous solutions has emerged as a hot research topic in wastewater treatment. Photocatalytic degradation is one the most effective methods to reduce ecological damage and environmental pollution. In this work, novel photocatalyst consisting Z-type heterojunction Bi2S3/Bi4Ti3O12 (BS/BTO) with visible light responses was prepared by an situ growth method, obtained material used for tetracycline hydrochloride (TC). The best performing BS/BTO-2, which exhibited high photocatalytic activity. rates TC reached 97.9% within 40 min illumination. demonstrated stability reproducibility even after 5 cycles. Electron spin resonance (EPR) tests quenching experiments established that ·O2– h+ were main species responsible elimination TC. On basis theoretical calculations experimental data, possible mechanism been proposed. structure, effectively increases absorption range decreases compounding efficiency photogenerated electrons holes, principally performance BS/BTO. Additionally, liquid chromatography–mass spectrometry (LC-MS) utilized investigate formation reaction intermediates. nontoxicity solution verified cultivating wheat seeds. This work offers guidance bismuth-based photocatalysts field sustainable treatments.
