FeS and Fe 3O 4 Co-modified biochar to build a highly resistant advanced oxidation process system for quinclorac degradation in irrigation water. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2023; 348:119492. [PMID: 37922748 DOI: 10.1016/j.jenvman.2023.119492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 10/16/2023] [Accepted: 10/28/2023] [Indexed: 11/07/2023]
Abstract
Advanced oxidation processes (AOPs), based on sulfate radical (SO4·-) produced by peroxymonosulfate (PMS), can effectively mineralize refractory organic pollutants. However, the coexistence of anions and natural organic matters in actual wastewater prevents the application of AOPs. A simple one-step method was used to prepare FeS/Fe3O4 co-modified biochar materials (FFB) that could activate PMS to degrade quinclorac (QNC) with a removal rate of 100%, even exhibiting optimum degradation of QNC reached 99.31% in irrigation water, demonstrating excellent anti-interference performance for co-existing anions and natural organic matter. Meanwhile, ecotoxicity analysis showed that the toxicity of degradation intermediates was lower than that of QNC. Characterization results demonstrated the even distribution of FeS and Fe3O4 onto biochar, supplying abundant Fe2+ to activate PMS producing reactive oxygen species (ROS), while the generated Fe3+ after reactive continue to be reduced with sulfur species to promote the cycle of Fe2+/Fe3+. The coexistence of ·OH, SO4·-, 1O2, and O2·- in the FFB/PMS-QNC system suggest the possession of two pathway with free radical and non-free radical pathways to degrade QNC. The density functional theory (DFT) was used to analyze the adsorption sites and adsorption energy of PMS, as well as the differential charge density, which further proved the generation of SO4·-, O2·- and 1O2. In addition, the electrochemical test results showed that electron transfer also played an important role in the degradation of QNC. This study provides a feasible approach for the removal of organic pollutants in actual water.

Bonding iron chalcogenides in a hierarchical structure for high-stability sodium storage. J Colloid Interface Sci 2023; 637:251-261. [PMID: 36706721 DOI: 10.1016/j.jcis.2023.01.056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Revised: 01/10/2023] [Accepted: 01/11/2023] [Indexed: 01/15/2023]
Abstract
Owing to price-boom and low-reserve of Lithium ion batteries (LIBs), cost-cutting and well-stocked sodium ion batteries (SIBs) attract a lot of attention, aiming to develop an effective energy storage and conversion equipment. As a typical anode for SIBs, Iron sulfide (FeS) is difficult to maintain the high theoretical capacity. Structural instability and inherent low conductivity limit the cyclic and rate performance of FeS. Herein, hierarchical architecture of FeS-FeSe2 coated with nitrogen-doped carbon (NC) is obtained by single-step solvothermal method and two-stage high-temperature treatments. Specifically, lattice imperfections provided by heterogeneous interfaces increase the Na+ storage sites and fasten ion/electron transfer. Synergistic effect induced by the hierarchical architecture effectively enhances the electrochemical activity and reduces the resistance, which contributes to the transfer kinetics of Na+. In addition, the phenomenon that heterogeneous interfaces provide more active site and extra migration Na+ path is also proved by density functional theory (DFT). As an anode for SIBs, FeS-FeSe2/NC (FSSe/C) delivers highly reversible capacity (704.5 mAh·g-1 after 120 cycles at 0.2 A·g-1), excellent rate performance (326.3 mAh·g-1 at 12 A·g-1) and long-lasting durability (492.3 mAh·g-1 after 1000 cycles at 4 A·g-1 with 100 % capacity retention). Notably, the full battery, assembled with FSSe/C and Na3V2(PO4)3/C (NVP/C), delivers reversible capacity of 252.1 mAh·g-1 after 300 cycles at 1 A·g-1. This work provides a facile method to construct a hierarchical architecture anode for high-performance SIBs.

Boosting electron transport process over multiple channels induced by S-doped carbon and Fe 7S 8 NPs interface toward high-efficiency antibiotics removal. JOURNAL OF HAZARDOUS MATERIALS 2023; 442:130115.

Abstract
The enhancement of electron transport process on multiple channels of C-Fe and C-S-Fe bonds between dual-reaction centres was investigated for stimulating the antibiotics degradation in Fenton-like processes. Herein, multiple channels structure of sulfur-doped carbon coupled Fe7S8 cluster through C-Fe bond and C-S-Fe bond was constructed through density functional theory (DFT), and S-doped carbon framework coated Fe7S8 nanoparticles (Fe7S8/SC) Fenton-like catalyst was prepared through hydrothermal and subsequent sulfuration process. The DFT calculations revealed that electrons are thermodynamically transferred from carbon to iron along both C-Fe and C-S-Fe bonds. The optimized Fe7S8/SC catalyst exhibited desirable catalytic property for Fenton-like degradation for various antibiotics, the removal of amoxicillin, norfloxacin, and tetracycline hydrochloride reach 98.9%, 97.8%, and 99.3% respectively within 40 min under neutral pH, and catalyst also demonstrated excellent cycle stability after five runs. The excellent degradation effect of antibiotics by Fenton-like catalyst was attributed to the intensified electron transport process by multiple electron transfer channels between dual reaction centres, making FeII easier to regenerate. This study spreads a new route for the enhancement of electron transport process in Fenton-like catalysts by constructing multiple channels.

Abstract
As a desirable candidate for lithium-ion batteries, potassium-ion batteries (PIBs) have aroused great interest because of their low cost and high power and energy densities. However, the insertion/extraction of K+ with a large radius (1.38 Å) usually bring about the destruction of the electrode materials. Here, ultrafine Fe7S8 nanocrystals are successfully implanted into hollow carbon nanospheres (Fe7S8@HCSs) via a facile solvothermal method and subsequent novel low-temperature sulfurization, which avoid the aggregation of Fe7S8 nanoparticles produced during high-temperature sulfidation. The ultrafine Fe7S8 nanoparticles and hollow carbon spheres can not only buffer the severe expansion/shrinkage of electrode materials caused by the repeated insertion/extraction of K+, but also provide additional accessible pathways for the high-rate K+ transmission. When tested as an anode material for PIBs, Fe7S8@HCSs achieve impressive K+ storage capacity of 523.2 mAh g-1 at 0.1 A g-1 after 100 cycles and remarkable rate capacity of 176.3 mAh g-1 at 5 A g-1. Further, assembling this anode with a K2NiFe(CN)6 cathode yields stable cycling performance, revealing its great potential for large-scale energy storage applications.

Abstract
The reasonable design of the precursor of a carbon-based nanocatalyst is an important pathway to improve catalytic performance. In this study, a simple solvothermal method was used to synthesize [Cu(TPT)(2,5-tdc)] ⋅ 2H2 O (Cu-MOF), which contains N and S atoms, in one step. Further in-situ carbonization of the Cu-MOF as the precursor was used to synthesize Cu/Cux S-embedded N,S-doped porous carbon (Cu/Cux S/NSC) composites. The catalytic activities of the prepared Cu/Cux S/NSC were investigated through catalytic reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP). The results show that the designed Cu/Cux S/NSC has exceptional catalytic activity and recycling stability, with a reaction rate constant of 0.0256 s-1 , and the conversion rate still exceeds 90 % after 15 cycles. Meanwhile, the efficient catalytic reduction of dyes (CR, MO, MB and RhB) confirmed its versatility. Finally, the active sites of the Cu/Cux S/NSC catalysts were analyzed, and a possible multicomponent synergistic catalytic mechanism was proposed.
