The preparation of ternary hexagonal boron carbon nitride (h-BCN) nanosheets was carried out by doping biomass glucose in situ into hexagonal boron nitride (h-BN). With this method, the construction of a two-dimensional (2D) semiconductor with tunable bandgap and characteristic adsorption ability toward organic molecules was achieved by maintaining the specific structure of h-BN and π-π interactions toward aromatic compounds. The ternary 2D h-BCN nanosheets worked effectively not only as a desirable adsorbent but also as an activator to benzene. Furthermore, the unique 2D h-BCN nanosheets were found to work as effective photocatalysts to convert benzene into phenol with less over-oxidation, leading to the development of a new type of Fenton oxidation reaction as the one-step visible light-driven hydroxylation of benzene. An optimal yield of 14.0% and its selectivity of 88.3% for the photocatalytic production of phenol from benzene were achieved by using h-BCN in the presence of FeCl 3 and H 2 O 2 in sustaining the same reactivity even after 4 cycles. This present study reports the latest development of phenol production from benzene by applying 2D h-BCN nanosheets as an artificial photosynthetic catalyst.

Nitrogen-doped mesoporous carbon/poly-o-phenylenediamine composites (denoted as N-MC/PoPD) were successfully synthesized by sacrificial hard template method followed by in situ oxidation polymerization initiated by FeCl3. It is revealed that the resultant N-MC/PoPD composites still remained original graphitization structure and narrow pore size distributions (centered at ∼3.8 nm) but suffered visibly monotonical decrease in specific surface area after oPD was increasingly polymerized onto N-MC with an increase of the mass ratio of PoPD to N-MC from 1:1 to 5:1. As supercapacitor electrode measured by galvanostatic charge-discharge in 6 mol L−1 KOH, a volcano curve was found when plotting specific capacitance of the N-MC/PoPD versus the mass ratio of N-MC to oPD; the N-MC/PoPD(2:1) with moderate surface area and the highest electrochemical conductivity delivered the highest specific capacitance of 229 F g−1 at a current density of 1 A g−1, which is twice of that obtained on the single N-MC with the maximum surface area. The remarkable enhancement in specific capacitance could be ascribed to the synergistic effect between two components of N-MC and PoPD.

Biochar, as a cost-effective and sustainable material, requires surface engineering for efficient removal of emerging contaminants like ibuprofen (IBU). This study demonstrates a facile one-step strategy using a FeCl 3 /urea deep eutectic solvent (DES) as an all-in-one modifier to concurrently introduce magnetization and N-doping during pyrolysis. By optimizing the pyrolysis temperature (500–800 °C) and peanut shell biomass/DES ratio (1:3–1:5), we identified that these parameters critically governed the biochar’s properties including graphitization, nitrogen content, defect density, surface functionalities and porosity. This enabled the synthesis of an N-doped magnetic biochar (PB600 1/5 ) that achieved a high IBU adsorption capacity of 175.75 mg/g, which was attributed to its favorable pore structure, abundant oxygen-containing groups, N functionalities and accessible Fe species. The adsorption followed pseudo-second-order kinetic and the Langmuir isotherm models, driven by mechanisms including pore filling, hydrogen bonding, Fe-complexation and π-related interactions. The biochar also exhibited excellent reusability and anti-interference ability. This work elucidates the synergistic interfacial mechanisms governing IBU adsorption and highlights the FeCl 3 /urea DES as an effective strategy for designing multifunctional biochar for pharmaceutical wastewater remediation.

Biomass flow fuel cells (BFFCs) are effective energy conversion technologies for converting biomass into electricity to realize a sustainable society. However, most of them depend on the thermal degradation of biomass, which is energy consumption and induces biomass polycondensation. Herein, we develop a novel solar-driven BFFC for converting lignin into electricity under sunlight at room temperature based on FeCl 3 /TiO 2 synergetic mediators, which endow a broad photo-absorption range and enhance absorption intensity for high photocatalytic activity. A new electron transfer chain is constructed by employing Fe 3+ to obtain electrons and efficiently promote electron-hole separation of TiO 2 . Meantime, the generated ·OH can depolymerize lignin rapidly. The BFFC achieved a power density of 64.4 mW/cm 2 at room temperature via sunlight irradiation with sodium lignosulfonate as fuel when paired with VO 2 + /VO 2+ catholyte. It can stably discharge and power LED light successfully. This work provides a sustainable and energy conservation approach for developing advanced biomass fuel cells.

In the field of cationic polymerization, ferric chloride (FeCl 3 ) has demonstrated exceptional initiation activity but is plagued by inherent structural instability. Consequently, enhancing the stability of this Lewis acid catalyst while preserving its high reactivity represents a critical research challenge with significant practical implications. This study introduces a novel approach by utilizing the [FeCl 3 ∙i-Pr 2 O] complex as a co-initiator, achieving a one-step protocol for the living cationic polymerization of isobutylene (IB) to produce highly reactive polyisobutylene (HRPIB) with α-olefin content reaching up to 94 %. The research systematically investigates the polymerization kinetics by examining the effects of isopropyl ether (i-Pr 2 O) content, reaction time, solvent polarity, and monomer concentration. Through comprehensive 1 H NMR structural analysis and Gaussian 09 computational simulations, the study reveals that i-Pr 2 O plays a dual-functional role: it not only stabilizes the FeCl 3 active centers but also promotes polyisobutylene chain termination, ultimately yielding three distinct olefin-terminated polyisobutylene derivatives. Building upon this innovative polymerization strategy, the research successfully demonstrates the synthesis of a PIBVE-b-PIB-b-PIBVE triblock copolymer using the [tBuDiCumCl] [FeCl 3 ∙i-Pr 2 O] initiation system.

The addition of Fe 3+ to TiO 2 is one of the effective methods to inhibit the recombination of photogenerated electrons and holes and thus improve the photocatalytic activity of TiO 2 . The effect of PVDF-PVP-TiO 2 -FeCl 3 (PPTFe) membrane filtration-photocatalytic system on the removal of trace concentration of sulfadiazine (SD) in water was evaluated. A two-factor four-level experiment was established to optimize 16 self-made modified membranes. The optimal membrane was then characterized in seven tests (SEM, EDS, membrane pure water flux, contact angle, porosity, mean pore size, ATR-FTIR), resulting in the optimal ratio (PPTFe membrane with 1.2 wt%TiO 2 and 0.8 wt%FeCl 3 ). Compared with the original membrane, the pore number, pore size, permeability, and hydrophilicity of the PPTFe membrane were all enhanced. The removal efficiency (92.63%) of SD by PPTFe membrane filtration-photocatalysis system was investigated. The reaction rate (0.0214 min −1 ) of the removal SD of the system was determined according to the pseudo-first-order kinetic model. The removal performance of membrane type, pH, and water quality parameters (Cl − , SO 4 2− , NO 3 − , HA) on PPTFe membrane filtration-photocatalytic system were also made a deep inquiry. The results reflected that acidic conditions (pH = 3) were beneficial to SD removal, the presence of Cl − , SO 4 2− , and HA could inhibit SD removal, while the existence of NO 3 − was unaffected. Furthermore, the removal rate of SD in the actual water body was displayed well in this system. Finally, the possible photocatalytic degradation mechanism was proposed. Graphical abstract

Iron (Fe) salt was applied extensively to remove phosphorus (P) in wastewater treatment plants (WWTPs). Exploring the formation mechanism of iron-phosphorus compounds (FePs) during the chemical P removal (CPR) process is beneficial to P recovery. In this study, the performance of P removal, FePs speciation analysis and the kinetics of P removal under different conditions (pH, Fe/P molar ratio (Fe/P mol ), type of Fe salt, dissolved organic matters) were comprehensively investigated. More than 95% of P was removed under the optimal conditions with pH = 4.7, Fe/P mol = 2, FeCl 3 or polymeric ferric sulfate (PFS) as the coagulant. The FePs formation mechanism was considerably influenced by reaction conditions. Iron-phosphate compounds were the dominant FePs species (>76%) at pH < 6.2, while more iron oxides were formed at pH ≥ 6.2 with decreased P removal efficiency. When the initial Fe/P mol was 2, iron-phosphate compound was the only product that was formed by the reaction between PO 4 3− and Fe(III) or Fe(II) ions directly. More iron oxides were generated when the initial Fe/P mol was 1 or 3. At Fe/P mol = 1, the Fe(III) was hydrolyzed to form iron oxides and trapped PO 4 3− , while at Fe/P mol = 3, iron-phosphate compounds were produced firstly and the remaining Fe(III) was hydrolyzed to form iron oxides. The pseudo-second-order kinetic model simulated the chemical P removal process well. The reaction rate of P with Fe(II) was slower than that with Fe(III), but complete removal was still achieved when the reaction time was more than 30 min. Poly-Fe salt exhibited a fast P removal rate, while the removal efficiency depended on its iron content. Organic matters in wastewater with large molecular weight and multiple functional groups (such as humic acids) inhibited P removal rate but hardly affect the removal amount. This study provides an insight into CPR by Fe salts and is beneficial for P recovery in WWTPs.

A series of MIL-53(Fe)-type materials, Fe(BDC)(DMF,F), were prepared by using different ratios of n(FeCl3)/n(FeCl2), which have varied amounts of Fe2+ in their frameworks. From FeCl3 to FeCl2, the structures of the synthesized samples transform from MIL-53(Fe) to Fe(BDC)(DMF,F). Along with this structure transformation, the crystal morphology goes through a striking change from a small irregular shape to a big triangular prism. This phenomenon indicates that the addition of FeCl2 is beneficial for the formation of a Fe(BDC)(DMF,F) structure. The catalytic activity of these iron-containing MOFs was tested in phenol degradation with hydrogen peroxide as an oxidant at near neutral pH and 35 °C. The degradation efficiency of these samples increases gradually from MIL-53(Fe) to Fe(BDC)(DMF,F). 57Fe Mössbauer spectra reveal that Fe2+ and Fe3+ coexist in the Fe(BDC)(DMF,F) framework, and the highest amount of Fe2+ in the sample prepared with mixed FeCl3 and FeCl2 is 26.0%. The result illustrates that the amount of Fe2+ in the samples can be controlled using varied n(FeCl3)/n(FeCl2) in the feed. The diverse amount of Fe2+ in this series of FeMOF materials exactly explains the distinction of reaction efficiency. The iron leaching tests, structures of the fresh and used catalysts, and the data of the recycling runs show that the Fe-containing MOFs are stable in this liquid-phase reaction.

The high acidity of stripping is one of the major problems that hinder the industrialization of the tributyl phosphate (TBP) + FeCl 3 system for lithium extraction from the salt lake brines with high Mg/Li ratio. In this study, a novel solvent extraction system, trialkylmethylammonium di(2-ethylhexyl)orthophosphinate ([N 1888 ][P 507 ]) + TBP + FeCl 3 , was developed to significantly reduce the difficulty of stripping and simplify the extraction process. The conditions of extraction and stripping were systematically studied in the present work. The results showed that Li + extraction efficiency could reach 61% under the optimal extraction parameters and Li + stripping ratio was 90% with a relative mild conditions of O/A = 10:1, [HCl] aq = 1.5 mol·L –1 . Also, combined with experimental results, FT-IR analysis, and UV analysis, the possible mechanisms of lithium extraction and stripping were put forward. Li + was extracted from the aqueous phase through the formation of [Li·2TBP][FeCl 4 ] adduct, meanwhile [N 1888 ][P 507 ] was just slightly involved in the extraction step. In the stripping procedure, the interaction between [FeCl 4 ] − and [Li·2TBP] + might be destroyed, and new possible complexes, [Li·2TBP] + , and [FeCl 4 ·TBP·P 507 ] 2− /[FeCl 4 ·P 507 ] 2− were formed in the organic phase. Additionally, the extraction efficiency of Li + remained above 70% while the organic phase was reused for six cycles. Compared with the traditional system, the addition of [N 1888 ][P 507 ] resulted in a slight decrease of Li + extraction efficiency (about 5%), the stripping acidity significantly reduced from 6 mol·L –1 HCl to 1.5 mol·L –1 HCl. This new extraction system showed a promising performance in selective extracting and easy stripping in lithium separation from the salt lake brines with high Mg/Li ratio.

Hydrophilic anti-fogging coatings face dual challenges of insufficient water resistance and poor weathering durability in practical applications. To address these issues, we propose a natural composite coating system integrating hyaluronic acid (HA), glycerol (Gly), FeCl 3 , and zinc oxide nanoparticles (ZnO-NPs) via a facile mixing strategy. Inspired by the mucin-mediated hydration dynamics of tear films, the HA framework constructs a self-replenishing layer to inhibit fogging while achieving underwater oleophobicity through surface hydration, effectively repelling oily contaminants. Glycerol maintains flexibility and hydration equilibrium through hydrogen-bonded water retention, whereas FeCl 3 crosslinking enhances mechanical strength and water stability via dynamic coordination bonds emulating tear film's ion-modulated self-repair, thereby resisting hydration-induced degradation. ZnO-NPs further endow the coating with photo-induced hydrophilicity. The optimized coating exhibits exceptional water resistance, weathering durability, and mechanical robustness, retaining high transmittance and stable hydrophilicity after 120 h of water immersion, 120 h of xenon lamp irradiation, 40 adhesion cycles, and 300 abrasion tests. Remarkably, the coating demonstrates rapid self-healing within 10 s and superior self-cleaning performance. This study proposes a sustainable strategy to synergistically enhance water resistance and weathering resistance.

Pathological coagulation within an injured artery and the subsequent cardiovascular complications, such as stroke and heart attack, greatly threaten human life. Inspired by the biochemical features of acute arterial thrombosis, such as abundant activated platelets and hydrogen peroxide (H 2 O 2 ), we constructed platelet-targeted theranostic nanoparticles (CyBA/PFM NPs) with H 2 O 2 -triggered photoacoustic contrast enhancement and antithrombotic capabilities. CyBA/PFM NPs were designed to target platelet-rich clots via fucoidan segment within the carrier, which could be activated by H 2 O 2 to produce fluorescent “CyOH” molecules, thus turning on the photoacoustic signal. CyBA/PFM NPs showed obvious amplification of fluorescence following incubation with fresh clots, exhibiting efficient scavenging ability of intracellular reactive oxygen species (ROS). In a FeCl 3 -induced mouse model of carotid thrombosis, CyBA/PFM NPs significantly amplified the photoacoustic contrast in thrombogenic tissues, effectively eliminated ROS within the occlusion site, and suppressed the thrombus formation , accompanied by a normalization of the soluble CD40L level. Given their accurate imaging potential, potent antithrombotic activities and acceptable biosafety, CyBA/PFM NPs hold strong potential as nanoscale theranostics for H 2 O 2 -correlated cardiovascular diseases. Statement of significance In this study, we developed a platelet-targeted and H 2 O 2 -triggered nanosystem self-assembled from phenylboronated fucoidan/maltodextrin polymers and responsive near-infrared probes. The fucoidan segment within the carrier could facilitate the specific delivery of the therapeutic polymers and probes to the platelet-rich arterial thrombus. In a mouse model of FeCl 3 -induced arterial thrombosis, the system could be activated by H 2 O 2 to produce fluorescent “CyOH” molecules, thus turning on the photoacoustic signal and specifically imaging thrombosed tissues. Besides, CyBA/PFM NPs significantly effectively eliminated ROS within the occlusion site and suppressed the thrombus formation. Given their theranostic potential and acceptable biosafety, this system has great potential for H 2 O 2 -correlated cardiovascular diseases.
