Quinoline ramifications possess a wide range of biological activities and potential pharmacological activities. Here, a concept of bifunctional solid acid photocatalyst TiO 2 /AC/SO 3 H with high acid density is firstly purposed for efficiently pure green synthesis of 2-quinoline carboxamide under ultraviolet-visible light irradiation. After sulfonation, the acid density of TiO 2 /AC is markedly larger than that of sole TiO 2 or AC, and the maximum yield of 2-quinoline carboxamide of 39% is obtained when the acid density of catalyst reaches 1.55 mmol/g. The new concept of bifunctional catalysis using solid acid and photocatalyst is potential for industrial application and instructive in green organic synthesis reactions which need radical and acid simultaneously.

The sex pheromone of the oriental armyworm, Mythimna separata (Walker), in China has always been confusing. It was initially considered as cis-11-hexadecenal (Z11-16:Ald) or cis-11-hexadecenyl acetate (Z11-16:Ac) and cis-11-hexadecenol (Z11-16:OH), as well as a mixture of these compounds. However, inconsistent results have frequently occurred using these compounds or mixtures in field trapping. Through gland analysis from individual females and nationwide field experiments, we identified two distinct types: Z11-16:Ald (aldehyde type or A type) and a mixture of Z11-16:Ac and Z11-16:OH (ester type or E type). Electroantennography (EAG) results indicated that both strains of males co-existed in the field. A strain of males had a strong EAG response to Z11-16:Ald but weak responses to Z11-16:Ac and Z11-16:OH, whereas E strain males had strong responses to Z11-16:Ac and Z11-16:OH but a weak response to Z11-16:Ald. Z11-16:OH identified in female E strain inhibited the attraction of A strain males to A type pheromones. Both A and E types of sex pheromone were respectively formulated and field evaluation (2014-2021) across > 20 provinces from southern to northern China showed geographic and generational variations. During overwintering, E strain males were predominantly caught in Hainan, Fujian, and Guangdong provinces, while A strain males were mainly trapped in Guangxi, Anhui, Sichuan, Jiangsu, and Jiangxi provinces. Subsequent generations exhibited mixed populations in most regions. These findings suggest regional adaptation and migration-driven hybridization. The study highlights the necessity of strain-specific pheromone blends for effective monitoring and control. This work resolves long-standing ambiguities in M. separata sex pheromone ecology.

Postoperative complications, such as air leakage, inflammation, and pleural adhesion, present considerable clinical challenges following lung resection procedures. These complications critically affect pulmonary recovery. In this study, we report a novel multifunctional self-adhesive bio-patch SIS-PEG-AC, which synergistically combines the biological activity of small intestinal submucosa (SIS), the effective sealing air leaks provided by polyethylene glycol (PEG) coating, and the anti-inflammatory effects of asiaticoside (AC). Compared to SIS, which exhibited limited tissue adhesion (0.73 kPa), the SIS-PEG-AC patch demonstrated a 30-fold increase in adhesiveness, achieving robust tissue adhesion (23.31 kPa) and significantly enhanced reparative capacity. AC delivered from the PEG hydrogel coating in a sustained manner, promoting the polarization of macrophages to M2 phenotype, to suppressing pro-inflammatory cytokine expression, thereby establishing a pro-regenerative ecological environment. The results of 28-day implantation on rat lung injury and 70-day implantation on pig lung wedge resection showed, the SIS-PEG-AC achieved excellent wound sealing, minimized postoperative pleural adhesions and significantly accelerated lung tissue regeneration. Compared with traditional synthetic polymers, the SIS-PEG-AC patch exhibited reduced adverse reactions, superior host tissue integration, and heightened control of the regenerative microenvironment, providing a promising approach to mitigate postoperative complications. Overall, this multifunctional patch demonstrates considerable clinical potential in lung repair, offering an effective strategy for thoracic surgical interventions.

Replacing the expensive Pt catalyst of counter electrodes (CEs) with a low-cost Pt-free catalyst has been regarded as one of the crucial steps for cost effectiveness of dye-sensitized solar cells (DSSCs). Herein, MnWO4 as a binary mixed oxide (MnO–WO3) has been prepared with (NH4)10H2(W2O7)6·xH2O and Mn(NO3)2·4H2O via a facile hydrothermal method. DSSCs using MnWO4 CEs show power conversion efficiency (PCE) of 4.93%. To improve the catalytic activity of MnWO4 CEs further, three proportions of MnWO4@AC mixed oxide composite catalysts have been fabricated via simple physical mixing MnWO4 with activated carbon (AC) by ball-milling. Moreover, the DSSCs with the MnWO4@AC composites CEs generate high PCE of 6.50, 6.45 and 6.12%, respectively, from MnWO4 : AC mass ratios of 1 : 2, 1 : 1 and 2 : 1 for the regeneration of traditional iodide/triiodide (I3−/I−) redox couples, which were superior to the pristine MnWO4, Pt- and AC-based counterpart 4.93%, 4.54% and 2.10% CEs under the same test conditions and method. The favorable performances make MnWO4@AC composites act as a new resource of electro-catalytic Pt-free materials for high-performance CEs in the encapsulation of DSSCs.

In this work, lead chloride (PbCl 2 ) and lead acetate trihydrate (Pb(Ac) 2 ·3H 2 O) mixed precursors are introduced to prepare perovskite films. PbCl 2 has been reported to enhance crystallinity but long annealing time is required. Pb(Ac) 2 ·3H 2 O is used because it is cheap and easy to get, and lead acetate offers fast crystallization process , meanwhile the trihydrate might improve the film stability. With an optimal blending ratio of the two precursors (1:1 mol ratio), compact and full-coverage perovskite film with large grain sizes (>1 µm) are obtained, and the speed of perovskite film formation is greatly accelerated. Moreover, the film prepared in a 1:1 mol ratio of the two precursors exhibits good moisture liability for several days under around 70% RH environment. As a result, the PbCl 2 : Pb(Ac) 2 ·3H 2 O (1:1) results in the highest efficiency of 14.77%. The findings in this work provide a facile way to improve the perovskite film quality and stability.

Background The aim of this study was to develop a class of novel MIL-53(Al) based composite with high phenolic compound adsorption capacity to treat highly toxic phenolic wastewater. Method MIL-53(Al)@AC-x composites with different AC loading ( x ) were constructed by combining MIL-53(Al) with cheap biomass AC derived from cheap rice husk. The adsorbents were characterized by various methods. Significant findings The results showed that the surface area and pore volume of all MIL-53(Al)@AC-x composites increased remarkably, which are much higher than those of pristine AC and MIL-53(Al). The p-nitrophenol adsorption rate of MIL-53(Al)@AC-10 was higher than pristine MIL-53(Al) by 36%. The adsorption performance decreased in the order of MIL-53(Al)@AC-10 > MIL-53(Al)@AC-15 > MIL-53(Al)@AC-5 > MIL-53(Al). The maximum adsorption capacity for p-nitrophenol of MIL-53(Al)@AC-10 reached 250 mg.g −1 , which are higher than the data reported in most literature. The fabrication of AC into MIL-53(Al) is a promising method to obtain a composite with high adsorption capacity and stability. The adsorption kinetics and isotherms fitted well with pseudo-second-order model and Langmiur model. The adsorption is mainly through the π-π and hydrogen bond interactions, and hydrophobic effect.

Electrochemical nitrogen reduction reaction(eNRR) is a promising strategy for ammonia production because of its mild reaction conditions, high theoretical conversion rate, and green pollution. However, the strong stability of N N triple bond and competitive hydrogen evolution reaction (HER) limit the Faraday efficiency and ammonia conversion of eNRR. In recent years, the structural design of catalysts combined with external field enhancement to enhance the AC magnetic field electrocatalytic reaction has received extensive attention. In this study, an eNRR catalyst ( x Fe-M-TiO 2 ) with a high concentration of oxygen vacancies was constructed by the defect engineering strategy. The ammonia conversion rate of eNRR of 1.5Fe-M-TiO 2 was 7.35 μg h −1 mg cat −1 , and the Faraday efficiency was 22.69 %, which was 2 % higher than that before doping. The spin–orbit coupling effect induced by the AC magnetic field further improved the eNRR activity, in which the Faraday efficiency increased to 52.14 % (increased by 150 %), and the ammonia yield increased to 13.37 μg h −1 mg cat −1 (increased by 5 %). After 80 h of eNRR, the current density of the catalyst became 95 % of the initial current density, and the stability was good. Density functional theory calculation showed that Fe doping did not change the reaction mechanism of eNRR but increased the concentration of oxygen vacancy, resulting in a 0.62 eV decrease in the energy barrier of the first hydrogenation of eNRR, which was conducive to the occurrence of eNRR.

This study presented a novel nano zero-valent iron anchored on activated carbon (nZVI@AC) catalyst, designed to overcome the inherent aggregation and oxidation limitations of bare nZVI. The nZVI@AC composite exhibited high catalytic activity for peracetic acid (PAA) activation, achieving complete degradation of sulfamethoxazole (SMX) within 10 min ( k obs = 0.3171 min -1 ). Characterizations confirmed that the AC support significantly enhanced electron transfer and increased the electron-donating capacity. This maximized exposure of active Fe 2+ species, which was crucial for efficient PAA activation and reactive oxygen species (ROS) generation. Radical quenching, electron paramagnetic resonance, and probe experiments identified hydroxyl radicals, singlet oxygen ( 1 O 2 ), and acetylperoxyl radicals as the primary ROS, with 1 O 2 playing the dominant role. The nZVI@AC/PAA system demonstrated remarkable stability and practical viability. This work established nZVI@AC as an efficient, stable, and versatile catalyst for PAA-based advanced oxidation processes, offering promising potential for water remediation applications.

The presence of abundant hydroxyl groups on the surface of Al2O3 can promote the dispersion of Ni species but produce an inactive NiAl2O4 phase at high temperatures. Moreover, the catalysts prepared by the conventional incipient wetness impregnation method lack the sites for the activation of CO2, which leads to coke deposition and thus affects the catalyst activity. The above restricts the utilization of Ni in conventional Ni/Al2O3 catalysts. In this paper, Al2O3 support was pre-treated by acetic acid to selectively remove hydroxyl groups without affecting the coordination environment of Al. Results revealed that the Al2O3 support after hydroxyl removal not only showed moderate metal–support interaction but also produced more sites for the adsorption and activation of the reactant, which significantly improves the utilization of nickel species and the stability of the catalyst. The conversion of CH4 and CO2 at 700 °C was as high as 88% and 90%, respectively, and has an excellent stability of 50 h. This study provides a feasible strategy for the design of highly active methane dry-reforming catalysts.

An activated carbon loaded Fe–Co nanometer material (AC/Fe–Co) was synthesized for catalytic degradation of coking wastewater. Synchronous fluorescence (SFS), Fourier transform infrared spectroscopy (FTIR) combined with two-dimensional correlation spectroscopy (2D-COS) were used to reveal the degradation of fluorescent components in coking wastewater dissolved organic matter (DOM). The results showed that nano-AC/Fe–Co catalyst can degrade coking wastewater in a broad range of pH (3–11). Total organic carbon (TOC) removal rate can reach 85.46%, and more than 86.00% of fluorescent components in DOM can be removed by nano-AC/Fe–Co catalyst. The result of 2D-SFS-COS indicated that the change sequence of these components was in the following order: 490, 400, 335, 325, 365, 380, 430, 273, 285, and 265 nm, indicating that humic-like at long wavelength (e.g. 490 nm and 400 nm) can be degraded preferentially, followed by fulvic-like (e.g. 335 nm, 325 nm, 365 nm, and 380 nm), humic-like (430 nm) and protein-like substances. Meanwhile, the preferential sequence of functional groups was in the following order: 1700–1900, 1548, 1080, 1214, 1010, 1652, 1140, and 1365 cm −1 . The result of moving window 2D-COS (MW2D-COS) showed that protein-, fulvic- and humic-like substances can also be removed within 0 to 30 min, which have occurred the transition at about 20 min. TOC removal rate by nano-AC/Fe–Co catalyst can reach more than 60.00% after three times reuse, suggested an excellent repeatability and stability. Herein, spectroscopic techniques in combination with 2D-COS can be used as feasible approaches to reveal the catalytic degradation characteristics of DOM in actual coking wastewater.

Driven by the “Dual Carbon” goals, supercapacitors have become critical energy storage devices for new energy electric vehicles. In this paper, a ZnFe2O4@ZnCo2O4core–shell cathode was prepared by a hydrothermal method followed by high-temperature annealing, and an AC@PANI composite anode was synthesized through in situ polymerization. The materials were characterized by SEM, TEM, XRD, XPS, nitrogen adsorption–desorption and electrochemical tests. The ZnFe2O4rod-like core provides mechanical stability, whereas the ZnCo2O4nanosheet shell increases the specific surface area and exposes more active sites. The cathode delivers 2133 F/g at 1 A/g with 94.4% retention after 10,000 cycles. The anode reaches 398 F/g at 1 A/g. The cathode delivers 2133 F/g at 1 A/g with 94.4% retention after 10,000 cycles. The anode reaches 398 F/g at 1 A/g. The assembled ZnFe2O4@ZnCo2O4//AC@PANI hybrid supercapacitor works in a wide voltage range of 0–1.6 V. It exhibits a specific capacitance of 157 F/g at 1 A/g and a high energy density of 54.7 Wh/kg at a power density of 1600 W/kg. The device retains 91.4% of its initial capacity after 10,000 charge–discharge cycles. This study offers a promising strategy for high-performance automotive supercapacitors.

Disintegration or redispersion of supported sintered gold nanoparticles (Au NPs) in the presence of alkyl halide can give catalyst regeneration or redispersion of sintered Au catalysts. The selectivity of alkyl halides, temperature and size distributions were investigated to elucidate the redispersion of Au NPs during halide-induced decomposition. This study proved that the alkyl halide induced the redispersion of sintered Au NPs which depended on the R–X (X = I, Br, Cl) bond dissociation energy (BDE) and thus provided a simple descriptor for the regeneration of inactive supported Au catalysts. A correlation between the BDE of R–X and dispersion efficiency was established. The tendency for disintegration and redispersion followed the R–X BDE of the alkyl halide. Compared to alkyl chlorides and bromides, iodides were more efficient for redispersing sintered Au NPs. As a descriptor, the BDE of R–I played a crucial role in particle redispersion. These findings provided insights into the mechanism of organic halide-induced Au NP disintegration and the effect of the halide type on the redispersion of sintered catalysts.
