Herein, we demonstrated that La substitution increased electron density on ≡Fe(III) sites in hydrated ferric oxide (HFO), thus strengthening the binding of phosphate on ≡Fe(III) sites and enhancing the intrinsic phosphate-adsorption capacity of ≡Fe(III) sites. Lanthanum substituted HFO (La-HFO) with 5 wt% dopant displayed a 3.4-fold increase in phosphate-adsorption capacity and 6.0-fold increase in adsorption rate, as well as the exceptional cyclability and stability. The increased electron density on ≡Fe(III) sites favored surface hydroxyl group dissociation, inducing more positively charged surface of HFO to attract the negatively charged phosphate anions, and resulting in the phosphate-adsorption mode transition from bidentate binuclear to bidentate mononuclear, more favorable for the utilization efficiency of ≡Fe(III) sites for phosphate-adsorption. Moreover, this strategy exhibits broad applicability beyond La, as evidenced by similar performance enhancements achieved with Ce substitution, highlighting its potential as a cost-effective strategy to enhance the intrinsic phosphate-adsorption performance of metal (hydr)oxides for advanced phosphate removal by regulating electron properties of the metal centers.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"6 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are still challenges in achieving satisfactory water-resistant bonding strength and toughness of these adhesives, due to the high polysaccharide content of raw materials and irrational energy dissipation paths. This study leverages the chemical selectivity of borate towards polysaccharides to develop a robust and tough soybean meal (SM)-based adhesive with hierarchical structure by constructing a graphene oxide-supported dynamic covalent network, labeled SM/BGO/BCS. Benefitting from hierarchical structure and dynamic covalent network, the SM/BGO/BCS adhesive exhibited favorable mechanical strength (dry shear strength of 2.35 MPa), and the water-resistance bonding strength (63 °C) is 1.62 MPa, to our knowledge, surpassing most of the existing reported SM-based adhesives. The work of debonding of SM/BGO/BCS adhesive is 1148.2 N/m, an increase of 234 % compared to the unmodified SM adhesive, which is toughened by stress transfer between the two phases (BGO and SM matrix), breaking the traditional approach of reinforcing polymers at the expense of toughness. In addition, the SM/BGO/BCS adhesive showed promising mildew resistance in both dry and wet states. According to the cost estimate, the cost of SM/BGO/BCS adhesive is comparable to that of commercially available urea-formaldehyde (UF) resin, making this strategy a viable insight for advancing the industrialization of plant protein adhesives.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"41 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, we aim to develop a series of efficient and stable phosphate-modified Sn-doped LaMnO3 catalysts (S-LMO/SnPx (x = 0, 3, 6, 9). S: SBA-15, as support). The experimental results demonstrate that S-LMO/SnP6 shows excellent catalytic activity of 1,2-dichloroethane (1,2-DCE, T90%=225.2 ℃). In addition, the S-LMO/SnP6 exhibits excellent stability in 5.0 vol% H2O and 50 h long-term tests, attributed to the protective effect of the phosphate layer on the metal active sites. Moreover, it also exhibits outstanding degradation activity for toluene (TOL), ethyl acetate (EA), and mixed VOCs, such as 1,2-DCE and TOL, 1,2-DCE and EA. Sn doping modulates the activity and mobility of lattice oxygen in LaMnO3. Meanwhile, phosphoric acid modification can regulate the microelectronic environment of the active metal sites on the surface, which can effectively prevent contact with polychlorinated by-products through the site isolation effect, thus inhibiting the generation of toxic by-products. The reaction pathway and mechanism of 1,2-DCE oxidation are further validated, summarized as: 1,2-DCE → vinyl chloride → vinyl alcohol → acetaldehyde → acetic acid → CO2 and H2O.

However, the low efficiency of heterogeneous catalysts still hinders its widespread application. Herein, FeWO4 synthesized by solvothermal method, using different water/alcohol mixed solvents, is employed to photocatalytically activate peroxymonosulfate (PMS) for antibiotics degradation. Due to differences in solvent polarity, dissolution kinetics and physicochemical properties of different alcohols (ethanol, ethylene glycol, glycerol), the morphology, specific surface area, pore structure, photoelectric properties, band gap structure, and consequently the photocatalytic activity of FeWO4, are significantly affected. It is found that as the alcoholic hydroxyl groups increase, the FeWO4 morphology gradually changes from nanorods to rice-grain-like nanoparticles, accompanied by an increase in specific surface-area and pores, an extension of the reaction-interface and light-absorption area, and an exposure of more active sites. Among them, FeWO4 (DZ:GI = 2:8), synthesized in a deionized water/glycerol mixed solvent with a volume ratio of 2:8, exhibits the highest photocatalytic activity for activating PMS. Within 15 mins, the removal rate of tetracycline (TC) catalyzed by FeWO4 (DZ:GI = 2:8) reaches 100 %. Free radical trapping experiments and electron paramagnetic resonance (EPR) spectra confirm that oxygen singlet (1O2) has a key role in TC degradation.

However, quickly producing halide perovskite single crystals (SCs) often leads to compromised material properties hindering high-end applications. To address this challenge, we developed a refined crystal growth methodology, low-temperature inverse temperature crystallization (LITC), tailored to enhance the quality of perovskite SCs while maintaining a relatively fast growth rate. Taking the synthesis of MAPbBr3 SCs as a model, isopropyl alcohol (IPA) was introduced into the precursors as an additive. The affinity of IPA for the crystal surface enables a modulated surface integration process and simultaneously impacts the charge of colloids within the precursor solutions to suppress undesirable nucleation. Thereafter, MAPbBr3 SCs can successfully grow under near-equilibrium conditions from 44 °C to 48 °C. Notably, a narrow full width at half maximum of 0.012° in the rocking curve of high-resolution X-ray diffraction was achieved, outperforming most inverse temperature crystallization (ITC) methods for SC synthesis. X-ray detectors fabricated with LITC SCs exhibited markedly improved performances. With meticulous surface integration control, this work advances the synthesis of high-quality perovskite SCs and paves the way for elevating the performance and durability of optoelectronic devices.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"77 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the improvement of intrinsic electrical conductivity remains a great challenge due to the tendency of LDHs to agglomerate, under-exposure of active sites, and under-developed internal pore structure. In this work, cobalt–nickel hydroxide modified N-doped hollow mesoporous carbon spheres (CoNi-LDH/N-HMCS) were designed and prepared as electrode materials. The results showed that N-HMCS was uniformly wrapped by CoNi-LDH nanosheets, which suppressed the volume change and structural collapse of CoNi-LDH during charging and discharging, increased the dispersion of the active material, and exposed more active sites. At the same time, the unique high specific surface area and hollow mesoporous structure of N-HMCS opens up an effective way for electrolyte ion transport, shortens the ion diffusion path, and reduces the diffusion resistance, thus improving the charge/discharge efficiency of the material. In addition, the presence of two different metal ions in CoNi-LDH provides more redox reaction sites and improves electrical charge storage capacity. Satisfactory, the CoNi-LDH/N-HMCS electrode material exhibits an ultra- high mass ratio capacitance with 2244.4 F g−1 (1 A g−1).
