Abstract :

Developing the transition metal catalysts with high reactivity for the sulfate radical (SO4 -center dot) based advanced oxidation processes (SR-AOPs) has been attracting numerous attentions. To improve the peroxymonosulfate (PMS) activation process mediated by Co-based catalysts, a vanadium-cobalt bimetallic catalyst (V@CoO) was fabricated by modification vanadium through a simple solvothermal method. The pollutants degradation experiments showed that the obtained V@CoO exhibited much higher performance on PMS activation (5.55-8.33 times larger of apparent rate constants) than pure CoO, and the V@CoO/PMS system could quickly degrade various organic contaminants within 5 min under the attack of both radicals (SO4 -center dot and O2-center dot) and non-radicals (1O2). The density functional theory (DFT) calculations and electrochemical tests revealed that the enhancing mechanism of V modification involved four aspects: (i) promoting the PMS adsorption on the surface of V@CoO; (ii) enhancing the electron transfer efficiency between V@CoO and PMS; (iii) activating PMS with V3+ and V4+ species; (iv) accelerating the circulation of Co2+ and Co3+, leading to the promotion on the production of reactive oxygen species (ROS). Furthermore, the V@CoO/PMS system also exhibited satisfactory stability in a broad pH range and good efficiency in the presence of co-existing components (HCO3-, NO3-, PO43- , Cl- and HA) in water. This study will provide new insights to designing high-performance, environment-friendly bimetal catalysts and some basis for the remediation of organic contaminants with SR-AOPs.

Abstract :

Developing adsorbents with high performance and long service life for effective extracting the trace organochlorine pesticides (OCPs) from real water is attracting numerous attentions. Herein, a self-standing covalent organic framework (COF-TpPa) membrane with fiber morphology was successfully synthesized by using electrospun nanofiber membranes as template and employed as solid-phase microextraction (SPME) coating for ultra-high sensitivity extraction and analysis of trace OCPs in water. The as-synthesized COF-TpPa membrane exhibited a high specific surface area (800.83 m(2) g(-1)), stable nanofibrous structure, and excellent chemical and thermal stability. Based on the COF-TpPa membrane, a new SPME analytical method in conjunction with gas chromatography-mass spectrometry (GC-MS) was established. This proposed method possessed favorable linearity in concentration of 0.05-2000 ng L-1, high sensitivity with enrichment factors ranging from 2175 to 5846, low limits of detection (0.001-0.150 ng L-1), satisfactory precision (RSD < 10 %), and excellent repeatability (>150 cycles), which was better than most of the reported works. Additionally, the density functional theory (DFT) calculations and XPS results demonstrated that the outstanding enrichment performance of the COF-TpPa membrane was owing to synergistic effect of pi-pi stacking effects, high specific surface area and hydrogen bonding. This work will expect to extend the applications of COF membrane to captures trace organic pollutants in complex environmental water, as well as offer a multiscale interpretation for the design of effective adsorbents.

Abstract :

Detecting trace endocrine disruptors in water is crucial for evaluating the water quality. In this work, a innovative modified polyacrylonitrile@cyanuric chloride-triphenylphosphine nanofiber membrane (PAN@CC-TPS) was prepared by in situ growing triazine porous organic polymers on the polyacrylonitrile (PAN) nanofibers, and used in the dispersive solid phase extraction (DSPE) to enrich trace nitrobenzene phenols (NPs) in water. The resluted PAN@CC-TPS nanofiber membrane consisted of numerous PAN nanofibers cover with CC-TPS solid spheres (similar to 2.50 mu m) and owned abundant functional groups, excellent enrichment performance and good stability. In addition, the method based on PAN@CC-TPS displayed outstanding capacity in detecting the trace nitrobenzene phenols, with 0.50-1.00 mu g/L of the quantification, 0.10-0.80 mu g/L of the detection limit, 85.35-113.55 % of the recovery efficiency, and 98.08-103.02 of the enrichment factor, which was comparable to most materials. Meanwhile, when PAN@CC-TPS was adopted in the real water samples (sea water and river water), the high enrichment factors and recovery percentages strongly confirmed the feasibility of PAN@CC-TPS for enriching and detecting the trace NPs. Besides, the related mechanism of extracting NPs on PAN@CC-TPS mainly involved the synergistic effect of hydrogen bonding, pi-pi stacking and hydrophobic effect.

Insights into Enhanced Peroxydisulfate Activation with B and Fe Co-Doped Biochar from Bark for the Rapid Degradation of Guaiacol SCIE

Abstract&Keyword Cite

Abstract :

A boron and iron co-doped biochar (B-Fe/biochar) from Masson pine bark was fabricated and used to activate peroxydisulfate (PDS) for the degradation of guaiacol (GL). The roles of the dopants and the contribution of the radical and non-radical oxidations were investigated. The results showed that the doping of boron and iron significantly improved the catalytic activity of the biochar catalyst with a GL removal efficiency of 98.30% within 30 min. The degradation of the GL mainly occurred through the generation of hydroxyl radicals (center dot OHs) and electron transfer on the biochar surface, and a non-radical degradation pathway dominated by direct electron transfer was proposed. Recycling the B-Fe/biochar showed low metal leaching from the catalyst and satisfactory long-term stability and reusability, providing potential insights into the use of metal and non-metal co-doped biochar catalysts for PDS activation.

Abstract :

As the cheap and efficient catalysts, the iron-based catalysts have been considered as one of the most promising catalysts for peroxydisulfate (PDS) activation and the development of high-performance iron-based catalysts are attracting growing attentions. In this work, a magnetic Fe-based catalysts (Fe/NC-1000) was obtained by using Fe modified ZIF-8 as the precursor and used to activate the PDS for the degradation of perfluorooctane sulphonate (PFOS). Morphology and structure analysis showed that the resulted Fe/NC-1000 catalyst was displayed porous spheres (40-60 nm) and mainly composed of Fe0, FeNx and carbon. When Fe/NC-1000 was employed to activate the PDS (0.1 g/L of catalyst dosage, 0.5 g/L of PDS dosage and at initial pH of 4.6), the Fe/NC-1000/PDS system exhibited excellent efficiency (97.9 & PLUSMN; 0.1) % for PFOS (10 mg/L) degradation within 30 min. The quenching tests and EPR results revealed that the Fe/NC-1000/PDS system degraded PFOS primarily through singlet oxygen (1O2) evolution and electron-transfer process. Besides, based on the degradation byproducts determined by LC-MS-MS, the PFOS first occurred de-sulfonation to form PFOA, and then the resulted PFOA underwent stepwise defluorination in the Fe/NC-1000/PDS system. Density Functional Theory (DFT) calculations and electrochemistry tests strongly confirmed that Fe/NC-1000 exhibited high electron transfer efficiency, resulting in promoted performance on activating PDS. Importantly, the results of Ecological Structure-Activity Relationship (ECOSAR) analysis showed that the intermediates were lowly toxic during the PFOS degradation, manifesting a green process for PFOS removal. This study would provide more understandings for the persulfate activation process mediated by Fe-based catalysts for Perfluorinated alkyl substances (PFAS) elimination.

Abstract :

In this study, the boron-doped iron-carbon composite (Fe@B/C-2) was prepared via a simple solvothermal and secondary calcination process by using iron metal-organic frameworks (Fe-MOFs) as precursor. The obtained Fe@B/C-2 possessed abundant active sites and low iron ion leaching, and exhibited excellent performance on peroxydisulfate (PDS) activation for efficient PFOS (10 mg/L) degradation (94 %) in 60 min, with 0.2 g/L of catalyst dosage, 1.0 g/L of PDS dosage and at 5.0 of initial pH. The radical scavenging and electron paramagnetic resonance (EPR) tests demonstrated that SO4 & sdot;- and & sdot;OH were the primary active species during PFOS elimination. Under the attack of these species, PFOS was first transformed into PFOA, followed by a sequential defluorination process, and lastly mineralized into CO2 and F. Notably, DFT results revealed that Fe species,-BC3/-BC2O structures on the carbon matrix performed crucial roles in PDS activation. The extraordinary catalytic activity of Fe@B/C-2 was attributable to the synergistic effects of Fe nanoparticles and the B-doped on carbon matrix. The doped B not only could activate the inert carbon skeleton and provided more catalytic centers, but also could accelerate the electron transfer efficiency, leading to a boost in PDS decomposition.

Abstract :

Heteroatomic co-doped carbon materials have broad application prospect in the field of persulfate-based advanced oxidation processes. In this paper, nitrogen and chlorine co-doped ZIF-8 derived porous carbon materials (NClC) were synthesized by a two-step pyrolysis method, as follows: 1.5 g ZIF-8 was transferred to a quartz boat, calcined for 6 h at 800. with a heating rate of 5 degrees C/min in a N-2 atmosphere, and cool naturally to room temperature; the black carbon material obtained was further treated with 0.5 mol/L HCl for 24 h to remove the residual Zn and then dried in a 60 degrees C oven to acquire N-doped porous carbon (NC); subsequently, 1.2 g NH4Cl was uniformly dissolved in 20 mL ultrapure water, and 0.15 g of the synthesized NC was added; after stirring and reaction for 5 h, the mixture was placed in a 60. oven to dry overnight; the dried sample was ground to a uniform powder and then calcined for 2 h at 700, 800, 900 or 1000 degrees C in a N-2 atmosphere to obtain NClCX, in which the "X" represents the secondary calcination temperature (degrees C). Additionally, NC900 was obtained by calcination of NC at 900. in the same way without any modification. The composition and structure of all carbon materials were characterized by field emission scanning electron microscope (FESEM), transmission electron microscope (TEM), X-ray diffraction (XRD), Raman, BET and X-ray photoelectron spectroscopy (XPS). Phenol was employed as a targeted contaminant to explore the performance of NClCX on PMS activation, and the results showed NClC900 exhibited excellent catalytic performance with 97.7% of phenol and 72.4% of total organic carbon (TOC) removal in 30 min. NClC900/PMS system presented excellent acid-base tolerance and anti-interference ability, which can effectively remove phenol over a broad pH range (pH=3 similar to 9) or under the interference of various anions (NO3-, Cl-, H2PO4-, HCO3-) and humic acid (HA). Moreover, the NClC900/PMS system performed outstanding feasibility in the removal of dyes, antibiotics, phenols, pesticide and purification of actual contaminated water samples. Cyclic experiments showed that NClC900 had good stability and could remove 72.1% of phenol after repeated use for 4 times. Quenching experiments, electron paramagnetic resonance and electrochemical analysis indicated that O-1(2) and surface-bound SO4 center dot- were the main active species for phenol degradation, and the graphite N, C-Cl of NClC900 were the key active sites for generating of O-1(2) and surface-bound SO4 center dot-.

Abstract :

A series of boron and nitrogen co-doped hierarchical porous carbon materials (BNC) were prepared via a facile one-step calcination process, and the catalytic performance of BNC on PMS activation for phenol removal was investigated. BNC-1 exhibited the optimal catalytic performance with a phenol degradation efficiency of 99.6% within 30 min. B, N co-doping strategy improved the specific surface areas (SSA) and total pore volumes (TPV) of carbon catalysts, providing them with abundant active sites, among which graphitic N and BC(3 )were identified as critical catalytic sites for PMS activation. Quenching tests, electron paramagnetic resonance (EPR) and electrochemical experiments demonstrated that singlet oxygen (O-1(2)) was the dominant active species while surface -bound sulfate radical (SO4 center dot-) played an inferior role in the BNC-1/PMS/Phenol system, and the role of hydroxyl radical (center dot OH), superoxide radical (O-2(center dot-)) and surface electron transport cannot be ignored either. The coexistence of radical and non-radical oxidation processes made BNC-1/PMS system have excellent acid-base tolerance (pH=3-11), anti-interference ability and pollutant mineralization performance (68.3% of TOC removal within 30 min). This study presented a high-efficiency and environment-friendly B, N co-doped metal-free catalyst for pollutants degradation via PMS activation and provided an in-depth research for the mechanism of PMS activation by BNC.
