Fe(II) is an excellent promoter for advanced oxidation processes (AOPs) because of its environmental ubiquity and low toxicity. This study among the first to characterize reaction peracetic acid (PAA) with ion apply Fe(II)/PAA AOP degradation micropollutants. PAA reacts (k = 1.10 × 105-1.56 104 M-1 s-1 at pH 3.0-8.1) much more rapidly than H2O2 outperforms coexistent Fe(II). While alone showed minimal reactivity methylene blue, naproxen, bisphenol-A, significant abatement (48-98%) compounds...
Photocatalytic nitrogen fixation represents a green alternative to the conventional Haber–Bosch process in conversion of ammonia. In this study, series Bi5O7Br nanostructures were synthesized via facile, low-temperature thermal treatment procedure, and their photocatalytic activity toward was evaluated compared. Spectroscopic measurements showed that tubular sample prepared at 40 °C (Bi5O7Br-40) exhibited highest electron-transfer rate among series, producing large number O2.– radicals...
Potassium periodate (PI, KIO4) was readily activated by Fe(II) under acidic conditions, resulting in the enhanced abatement of organic contaminants 2 min, with decay ratios selected pollutants even outnumbered those Fe(II)/peroxymonosulfate and Fe(II)/peroxydisulfate processes identical conditions. Both 18O isotope labeling techniques using methyl phenyl sulfoxide (PMSO) as substrate X-ray absorption near-edge structure spectroscopy provided conclusive evidences for generation high-valent...
A simple method for preparing 5-fluorouracil surface-functionalized selenium nanoparticles (5FU-SeNPs) with enhanced anticancer activity has been demonstrated in the present study. Spherical SeNPs were capped 5FU through formation of Se-O and Se-N bonds physical adsorption, leading to stable structure conjugates. surface decoration significantly cellular uptake endocytosis. panel five human cancer cell lines was shown be susceptible 5FU-SeNPs, IC(50) values ranging from 6.2 14.4 μM. Despite...
Peracetic acid (PAA) is increasingly used as an alternative disinfectant and its advanced oxidation processes (AOPs) could be useful for pollutant degradation. Co(II) or Co(III) can activate PAA to produce acetyloxyl (CH3C(O)O•) acetylperoxyl (CH3C(O)OO•) radicals with little •OH radical formation, Co(II)/Co(III) cycled. For the first time, this study determined reaction rates of (kPAA,Co(II) = 1.70 × 101 6.67 102 M-1·s-1) (kPAA,Co(III) 3.91 100 4.57 ions over initial pH 3.0-8.2 evaluated 30...
Peroxymonosulfate (PMS)-based advanced oxidation processes (PMS-AOPs) as an efficient strategy for organic degradation are highly dependent on catalyst design and structured active sites. However, the identification of sites their relationship with reaction mechanisms not fully understood a composite due to complex structure. Herein, we developed family Co encapsulated in N-doped carbons (Co-PCN) tailored types contents via manipulated pyrolysis PMS activation ciprofloxacin (CIP)...
In this study, the previously overlooked effects of contaminants' molecular structure on their degradation efficiencies and dominant reactive oxygen species (ROS) in advanced oxidation processes (AOPs) are investigated with a peroxymonosulfate (PMS) activation system selected as typical AOP system. Averagely, 19 contaminants discrepant CoCaAl-LDO/PMS production SO4•-, •OH, 1O2. Density functional theory calculations indicated that compounds high EHOMO, low-energy gap (ΔE = ELUMO - EHOMO),...
The current review summarizes the recent advances in nanotechnology for PhACs removal and proposes possible further research directions.
Herein, a silicate-enhanced flow-through electro-Fenton system with nanoconfined catalyst was rationally designed and demonstrated for the highly efficient, rapid, selective degradation of antibiotic tetracycline. The key active component this is Fe2O3 nanoparticle filled carbon nanotube (Fe2O3-in-CNT) filter. Under an electric field, composite filter enabled in situ H2O2 generation, which converted to reactive oxygen species accompanied by redox cycling Fe3+/Fe2+. presence silicate...
Material-enhanced heterogonous peroxymonosulfate (PMS) activation on emerging organic pollutant degradation has attracted intensive attention, and a challenge is the electron transfer efficiency from material to PMS for radical production. Herein, an interface architecture of Co(OH)2 nanosheets growing KNbO3 perovskite [Co(OH)2/KNbO3] was developed, which showed high catalytic activity in activation. A reaction rate constant (k1) 0.631 min-1 complete removal pazufloxacin within 5 min were...
Many reagents as electron sacrificers have been recently investigated to induce decomposition of permanganate (KMnO4) produce highly reactive intermediate Mn species toward oxidation organic contaminants; however, this strategy meanwhile causes low KMnO4 utilization efficiency. This study surprisingly found that graphite can mediate direct transfer from organics (e.g., sulfamethoxazole (SMX)) KMnO4, resulting in high efficiency, rather than reductive sites graphite-induced conversion...
