Background Excess phosphorus in aquatic environments causes eutrophication. Low-valence inorganic and dissolved organic phosphorus are harder to remove than orthophosphate. These species usually require oxidation before separation, whereas oxidation alone cannot reduce total phosphorus (TP), resulting in multi-stage treatment processes. Methods This study explores a waste-derived cerium-modified CoFe 2 O 4 @biochar composite (ECB) prepared from crab shells for synchronous oxidation and adsorption of phosphorus species in water. Scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS), were conducted for material characterization. Electron spin resonance (ESR) and radical quenching tests were used to identify reactive oxygen species. Significant findings The ECB/peroxymonosulfate (PMS) system removed 95.6% of P(III) within 30 min at neutral pH, reducing residual TP below 0.5 mg/L. PMS addition accelerated phosphorus removal by oxidizing P(III) to phosphate, which was captured by surface cerium-containing sites. The adsorption followed pseudo-first-order kinetics. Mechanistic results showed CoFe 2 O 4 @biochar activated PMS to generate SO 4 •− as the main reactive species, and electrostatic interaction and ligand exchange were responsible for phosphate capture. The ECB/PMS system was effective for dissolved organic phosphonates and exhibited magnetic separability, reusability, and low metal leaching. This research presents an efficient one-step strategy for phosphorus control and recovery, supporting cleaner production and circular utilization of crab shell waste.

With the increasing demand for the co-encapsulation and controlled delivery of bioactive compounds, the design of liquid-based carriers has garnered considerable attention. Vitamin D 3 and riboflavin sodium phosphate (RP) suffer from poor stability and low bioavailability; nevertheless, high internal phase Pickering emulsions (HIPPEs) feature a tunable microstructure that allows for effective compartmentalization of multiple components. In this study, HIPPEs stabilized by egg white peptide (EWP)-konjac glucomannan (KGM) co-assemblies were constructed as a versatile vehicle for the co-delivery of vitamin D 3 and RP. EWP-KGM co-assemblies were comprehensively characterized using multispectral techniques and structural analyses. The EWP@KGM co-assembly (mass ratio 10:5) exhibited enhanced emulsifying activity index (EAI: 15.12 m 2 /g, 3.74-fold higher than EWP) and emulsifying stability index (ESI: 736.60 min, 53-fold higher than EWP), attributed to increased interfacial thickness and steric hindrance. All HIPPEs demonstrated shear-thinning behavior, gel-like viscoelasticity (G′ > G″), and long-term storage stability. Under simulated gastrointestinal digestion, EWP-KGM-HIPPEs protected RP integrity and improved vitamin D 3 bioaccessibility. FFA release kinetics followed Korsmeyer-Peppas model, indicating anomalous transport driven by diffusion and matrix relaxation. This study presents a promising platform for the dual encapsulation of bioactives with contrasting polarities, paving the way for applications in nutraceuticals.

Antibacterial poly[(acryloyloxyethyl trimethyl ammonium chloride)-co-(hydroxyethyl methacrylate)-co-(methyl methacrylate)] (P(DAC-HEMA-MMA)) was designed and synthesized via aqueous copolymerization using DAC, HEMA, and MMA as cationic, functional, and hydrophobic monomer, respectively. The structure, thermal property and elemental composition of the copolymer were characterized by multiple techniques. Antibacterial performance test showed that minimum inhibitory concentrations (MIC) of P(DAC-HEMA-MMA) against both Escherichia coli and Staphylococcus aureus were 3.12 mg/mL. When P(DAC-HEMA-MMA) was applied to the aged paper sample, its tensile strength, folding endurance, and tearing resistance were increased by 88.4%, 118.7%, and 60.5%, respectively, with a whiteness improvement of 21.5%. After dry-heat aging, it still remained excellent anti-aging ability. In addition, the antibacterial rates of the treated paper sample against E. coli and S. aureus reached 69.2% and 97.7%, respectively, and the treated one maintains unchangeable antibacterial performance after exposing to the ambient condition for 3 months; the water contact angle reached 118.9°, higher than that of the original paper sample, and however, it was decreased over time. All the results confirmed P(DAC-HEMA-MMA) treatment can effectively enhance the mechanical properties of the paper samples, and endow them with wonderful antibacterial and hydrophobic properties, thus holding multifunctional application in the field of paper postprocessing.

CO is an invisible killer that severely threatens the safety of trapped personnel in fire disasters. The existing CO removal approaches are passive and ineffective, which could not satisfy the emergency rescue needs. An active and synchronous CO removal approach (ASCR) based on catalytic oxidation is proposed. By spraying dry powder extinguishant and catalyst powder, the isolation layer and oxidation layer are formed on the fuel surface. CO removal is achieved by both combustion suppression and CO oxidation methods. The synthesized Co-La 0.1 catalyst exhibited superior catalytic activity, thermal stability , and selectivity, which met the application requirements of the ASCR approach. The results of lab-scall tests demonstrated that the CO concentration in the smoke flow decreased from 135 ppm to 0 ppm immediately once employing the ASCR approach. Full-scale tests in the confined tunnel further verified the practical application performance. With spraying 2 kg extinguishant and 0.9 kg catalyst powder, CO concentration increased merely by ∼ 20 ppm within 50 min, which was far lower than that without taking any disposal measures (∼800 ppm). This approach can effectively control the CO concentration below the safety threshold in fire disasters and is significant for emergency rescue.

In this paper, a series of bimetallic catalysts with different Ni/Co ratios were prepared by co-impregnation method for application in methane dry reforming reaction. The effects of different Ni/Co ratios on the catalyst performance were investigated. The catalysts were characterized by XRD, BET, H 2 -TPR, TG, TEM and FTIR. The results showed that after the introduction of a certain amount of Co, the synergistic effect between Ni and Co enhanced the active component-carrier interaction, thus improving the dispersion of the active component of the catalyst, reducing the particle size of the metal, and increasing the activity of the catalyst. Meanwhile, the mechanistic study showed that the introduction of Co species with strong oxygen affinity facilitated the formation of oxygen vacancies. It makes the catalysts contain higher lattice oxygen and carbonate species, which was conducive to the elimination of carbon accumulation, thus improving the stability of catalysts. Therefore, the 10Ni-8Co-10Y/WC-AC catalyst exhibited excellent dry reforming of methane (DRM) performance at a Ni/Co ratio of 5:4. The conversions of CO 2 and CH 4 were 95 % and 88 % at 800 °C under atmospheric pressure, respectively.

Fe-N-C catalysts have served as ideal catalysts for oxygen reduction reaction (ORR), but the strong adsorption to ORR-relevant intermediates and less utilization of Fe-N x sites endow those catalysts with inferior performance. Here, an efficient catalyst consisted of Fe-N x species and FeF 2 /Fe 3 C nanoparticles co-anchored on N, F co-doped carbon nanotubes (Fe-NF-CNTs) has been constructed through a surface modification strategy. Sodium trifluoroacetate as functional linker modified on metal-organic framework surface promotes to form abundant and accessible active sites. FeF 2 /Fe 3 C nanoparticles and hydrogen fluoride generated in pyrolysis process facilitate to construct N, F co-doped CNTs with defects and holes. N, F co-doping modifies the adsorption characteristic of Fe-N x sites, while CNTs improve the accessibility of active sites and the capability of material transport. Therefore, Fe-NF-CNTs exhibits outstanding activity (E 1/2 = 0.85 V) and stabilization (ΔE = 6 mV, 10k cycles). Impressively, Fe-NF-CNTs delivers high power density (144 and 68 mW cm –2 ) and cycle stability (300 and 60 h) in liquid and flexible Zn-air batteries, respectively. This work provides a surface modification strategy to guide the tuning of electronic structure of efficient ORR catalysts designed for renewable green energy.

Herein, low molecular weight poly(vinyl chloride- co -n-butyl acrylate- co -vinyl acetate) (PCBV) ternary copolymers with varied copolymer composition was employed as a novel polymeric lubricant in rigid PVC. The lubrication effect of PCBVs on the melting process and mechanical properties of the final PVC products were fully investigated. The results indicated that PCBV can serve either as an internal or as an external lubricant depending on its composition. PCBV-45.5 terpolymer (PBA% ~ 45.5%) exhibits outstanding balance both internal and external lubricating roles. SEM-EDS results show that addition PCBV-45.5 form a film on the surface of PVC grains as similar as that adding both internal and external lubricants. Fusion characteristics and DMTA demonstrate that PCBV-45.5 prolongs the fusion time (26% extension, 1.5 phr) and reduces the glass transition temperature (4.0 °C, 1.5 phr). Finally, the mechanical properties of rigid PVC have been greatly improved by using 1.5 phr PCBV-45.5. In detail, the tensile strength increased from 54 to 59 MPa and the elongation at break increased from 10% to 30%, respectively. Meanwhile, the impact strength of PVC/PCBV-45.5 is 3.6 times that of the blend without addition. The excellent performance of PCBV exhibited great potential as a polymeric lubricant candidate in rigid PVC composites. Graphical

The water treatment performance of membrane filtration is usually restricted via the paradox between permeability and selectivity. Herein, the nitrogen doped porous carbon supported Co catalysts (CoNPC), serving as both porous filler and peroxymonosulfate (PMS) activator, were firstly filled into polyvinylidene fluoride (PVDF) matrix to construct a novel mixed matrix catalytic membrane (CoNPC@PVDF) for enhanced water purification. Owing to the robust binding between CoNPC and PVDF, a high loading (50 wt%) and even dispersion of CoNPC were realized in CoNPC@PVDF, and its permeability and selectivity were both improved with the increase of CoNPC content. The optimum CoNPC@PVDF with PMS activation assistance (FCP) exhibited effective phenol removal at short retention time (1.5 s) and high permeability (256.6 L m −2 h −1 bar −1 ). The performance of CoNPC@PVDF FCP was 2.9 and 2.5 times higher than that of filtration alone and PMS activation alone, respectively, and even dramatically outweighed the reported catalytic membranes and heterogeneous catalysts. The outstanding performance of CoNPC@PVDF catalytic membrane was mainly attributed to its thin membrane structure and high filling degree of CoNPC, resulting in ultrahigh mass transfer rate (1.8 × 10 −4 m s −1 ) and more exposed active sites for enhanced PMS activation into radicals (mainly •OH and SO 4 •− ) towards pollutant removal.

We discovered that triethanolamine (TEOA) can break Co–N bonds in a 2D Co(II)-imidazole MOF, {[Co(TIB) 2 (H 2 O) 4 ]SO 4 } (TIB stands for 1,3,5-tris(1-imidazolyl) benzene) (CoTIB) to form the ultrafine fragments of CoTIB with sizes <5.6 nm under stirring, which are highly efficient and selective (>99%) heterogenous cocatalysts for the visible-light-driven photocatalytic CO 2 reduction reaction to CO. The efficiency of the ultrafine fragments of CoTIB (2.0–4.2 nm) reaches 42.7 mmol g −1 h −1 or a TOF of 33.7 h −1 based on Co atoms, which are among the best of heterogenous cocatalyst for photocatalytic CO 2 RR to CO systems. They are also highly stable under stirring with a TON greater than 909 in 54 h. The ultrafine fragments of CoTIB in mixed solvents were obtained by filtration, using a 0.22-μm filter head, of the 9-h stirred mixture of CoTIB/CH 3 CN/TEOA/trace-H 2 O or the 9-h reaction mixture using 1.0 mg of CoTIB. The fragments of CoTIB in these filtrates were characterized by high-resolution mass spectrometry (HRMS), size distribution and Zeta-potential measurements, ICP-MS, as well as Linear-Sweep-Voltammetry (LSV) measurements. The formation process of these nanoparticles and the mechanism of the photocatalytic CO 2 RRs were proposed. In addition, this work provides an easy method for making ultrafine fragments (<10 nm) of a Co(II)-imidazole MOF or other MOFs, which could also be viewed as MOF nanoparticles or quantum dots stabilized by coordination of TEOA molecules.

It has drawn extensive research interest to integrate luminescent ligands into metal-organic frameworks as luminescent materials due to striking luminescent properties. In this work, a Co-MOF with weak fluorescence emission , [Co(OBA)(2,2′-BPY)], was synthesized by a mixed solvothermal route with Co(NO 3 ) 2 as the Co 2+ ion source, 4,4′-Oxybis(benzoic acid) (OBA) and 2,2′-Bipyridyl (2,2′-BPY) as the ligands. Its fluorescence was obviously enhanced through integrating a small amount of luminescent ligands: 2-aminoterephthalic acid. Interestingly, the above enhanced fluorescence could be selectively quenched by the organophosphorus pesticides with p-nitrophenyl group such as p-nitrophenyl phosphate (PNPP) and bis(p-nitrophenyl) phosphate (BNPP) in water systems. As a case, the detection limit towards PNPP was up to 352 nM (0.07 mg kg −1 ), which is far lower than the standards for similar pesticide residues in fruits in China (0.1–0.6 mg kg −1 ) [ 1 ]. At the same time, the above phenomenon of the fluorescence quenching was not interfered from some other pesticides, metallic ions, amino acids and aromatic nitrocompounds, implying the present fluorescent material has potential application as a highly selective probe for detecting PNPP pesticide residues in food and domestic water. Furthermore, a possible quenching mechanism was discussed.

The synthesis of Vis-light driven catalysts with high photocatalytic performance and efficient activation of persulfate requires new strategies. Herein, a multistage structural tuning graphitic carbon nitride co-modified by Co, S (pg-C 3 N 4 /Co 3 O 4 /CoS) was synthesized for the first time through in-situ template method and microwave sulfurization treatment. A photocatalysis-PMS oxidation coupling system was also proposed. The results showed that the introduction of cobalt could improve the photocatalysis and PMS activation efficiency of the graphitic carbon nitride. Further sulfurization treatment could generate more active sites for PMS activation and increase the interlayer distance of carbon nitride to broaden the absorption range of Vis-light. Density functional theory (DFT) calculations indicated the migration of electrons from carbon nitride to CoS promoted the recycling of Co 3+ /Co 2+ . In the coupling system, BPF 50 mL (30 mg L -1 ) was degraded by 99% in 10 min with 0.1 g L -1 catalyst and 0.32 mmol L -1 PMS. The degradation rate was 4 times faster than that of pure PMS system under visible light. Notably, BPF was effectively mineralized and TOC removal rate reached 90%. The stability and recycling experiments showed that pg-C 3 N 4 /Co 3 O 4 /CoS maintained high catalytic performance under complex matrix and multiple cycles, and could be quickly separated and recovered due to the magnetic Co 3 O 4 . This work will provide a new strategy for the development of multi performance catalytic materials, and the proposed photocatalysis-PMS coupling system has huge potential for the wastewater treatment.

The Zn-air battery is a promising next-generation battery because of the higher energy density and safety compared with the Li-ion battery. However, the Zn-air battery suffers from huge energy loss and poor cycling performance, which are due to the sluggish kinetics of oxygen reduction/evolution reactions (ORR/OER) and the instability of bifunctional catalysts . The state-of-the-art bifunctional catalyst is the composite of Pt and Ir/Ru oxides, which is hindered by the scarce resource and high cost. Therefore, developing low-cost and high-efficient bifunctional non-noble metal-based catalysts is essential to the deployment of Zn-air batteries. Herein, we report a dual-nitrogen-source mediated pyrolysis route to rationally design and synthesize the hybrid Co/Co–N–C bifunctional catalyst. The tailored catalyst consisting of carbon confined Co nanoparticles and atomically dispersed Co–N–C moiety is identified. Remarkably, the dual-nitrogen-source derived Co/Co–N–C catalyst demonstrates excellent electrochemical performances with a half-wave potential of 0.882 V for ORR and a potential of 1.640 V at 10 mA cm −2 for OER; reasonably, the bifunctionality of Co/Co–N–C, which is supported by the excellent self-breathing Zn-air battery performance (the maximum energy density of 897.1 Wh kg Zn −1 ; no obvious degradation within 167h cycling). The abundant Co-Nx sites and metallic Co nanoparticles synergistically boost the ORR and OER.
