The development of effective catalysts for producing H2 from water electrolysis is gaining a lot of interest in an effort to reduce dependence on fossil fuels. To improve catalyst charge transport capabilities, active sites must be prevented from aggregating during material production. In this present research, we have fabricated the BaFeO3 nanoparticles embedded on rGO nanosheet using a hydrothermal approach for electrochemical HER in a basic media. Analytical techniques are carried out for physical, morphological, and surface area analysis. The optimized BaFeO3/rGO demonstrates efficient HER performance compared to pristine BaFeO3, exhibits reduced HER overpotential of 219 mV at −10 mA/cm2 and a 64 mV/dec Tafel value follows a Volmer-Heyrovsky mechanism for composite catalyst. Moreover, the electrocatalyst showed a double-layer capacitance (Cdl) value (4.05 mF/cm2), minor solution resistance (1.23 Ω), and durability over 50 h. Hence, these outcomes present a novel approach for designing efficient HER catalysts by integrating perovskite transition metal oxides with two-dimensional materials.\u0000 </div>","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"73 10","pages":"1660-1670"},"PeriodicalIF":2.0,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149177709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike independent photocatalytic and PEC systems reported in most literature, all contrast experiments adopt identical catalyst loading amounts and electrode specifications, with applied bias as the only variable to reliably reveal the electric field synergistic effect. Owing to the unique advantages of PEC technology and the excellent properties of organic–inorganic heterostructures, the PEC/PTTE-Sb2S3 system exhibits extremely high activity and stability in removing MB under visible light irradiation and achieves a relatively high degradation efficiency. The kinetic rate constants of the PEC/PTTE-Sb2S3 system are approximately 14.6, 2.7, 2.5, and 2.1 times higher than those of the photolysis, photocatalysis (HP)/Sb2S3, HP/PTTE-Sb2S3, and PEC/Sb2S3 systems, respectively.

This study investigates the kinetics of gas–liquid heterogeneous acetic acid chlorination using elemental sulfur as a catalyst precursor to establish a scientific basis for process optimization. A consecutive-parallel reaction mechanism was proposed incorporating acetic acid consumption, acetyl chloride conversion, MCA formation, and dichloroacetic acid (DCA) formation. Kinetic parameters were determined at 353, 363, 373, and 383 K in a steel bubble column reactor with fixed initial sulfur concentration (1.92 mol/L) and Cl2 space velocity (4.028 L L−1 h−1). The activation energy for DCA formation (87.55 kJ mol−1) was substantially higher than that for MCA accumulation (52.40 kJ mol−1). Relative rate analysis revealed that k3/k4 decreases continuously from 1.83 at 353 K to 0.76 at 383 K, confirming that lower temperatures favor MCA selectivity. The proposed kinetic model showed excellent agreement with experimental data (R2 > 0.98). Based on the kinetic analysis, three optimization strategies were derived: maintaining high acetic acid concentration, dynamic adjustment of Cl2 feed rate, and implementation of a decreasing temperature–time profile. This work provides a scientific basis for optimizing industrial MCA synthesis using low-cost sulfur as a catalyst precursor.\u0000 </div>","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"73 10","pages":"1625-1635"},"PeriodicalIF":2.0,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149177303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, cationic bottlebrush copolymers composed of poly(ethylene glycol) methyl ether methacrylate (PEGMA) and quaternized 2-(dimethylamino)ethyl methacrylate (QDMAEMA) were synthesized via controllable atom transfer radical polymerization. The as-prepared bottlebrush copolymers were subsequently blended with polyethersulfone to fabricate robust membranes with combined antibacterial and antifouling properties. Compared to their linear analogues, the bottlebrush copolymer-based membranes exhibited enhanced antibacterial efficacy against Escherichia coli and Staphylococcus aureus, along with faster bactericidal kinetics. This improvement is attributed to the increased surface exposure of quaternary ammonium groups in the bottlebrush architectures, which strengthen electrostatic interactions with negatively charged bacteria. Additionally, the densely packed side-chain arrangement stabilized hydration layers, thereby suppressing protein adsorption and bacterial adhesion. Notably, the optimized bottlebrush copolymer-based membranes exhibited excellent durability, retaining over 99% antibacterial activity after five cycles.

By systematically tuning the pore size of the p-SiO2 (2.1–5.4 nm) and the Cl/Br molar ratios (Cl:Br = 2:1, 1:1, 1:2, and 0:3), continuous emission tuning from blue (460 nm) to green (520 nm) with narrow bandwidth (FWHM < 27 nm) was achieved. The nanoconfinement provided by p-SiO2 effectively restricted perovskite crystal growth and reduced nonradiative recombination, while the cross-linked silica-gel coating served as an external barrier against moisture ingress. Among the investigated conditions, the p-SiO2 synthesized at pH 2 exhibited a narrow pore size distribution (~2.1 nm), providing effective confinement for perovskite crystallization. As a result, the CsPbX3@p-SiO2/SG phosphors retained approximately 90% of their initial photoluminescence intensity without detectable spectral shifts after 200 days of water immersion.

Accordingly, the choice of donor, π-bridge and the acceptor is very crucial while designing the dye's architecture. In this work, the influence of one additional donor in the basic D-π-A structure of thiophene-substituted triphenylamine-donor based organic dye (metal free) has been investigated. Dyes having D-π-A and D-D′-π-A architecture were designed. In the dyes with D-D′-π-A architecture, one donor, thiophene-substituted triphenylamine (D) was kept fixed while the other (D′) was varied to study the effect of the additional donor in a linear chain. Two π-spacers were used to design 10 molecules. Geometry, charge transfer and optoelectronic properties of the proposed molecules have been studied. For this, the dyes were adsorbed on the nanocrystalline surface of the semiconductor (TiO2). Theoretical evaluation of various parameters such as energies of frontier molecular orbitals, energy gap between HOMO and LUMO, wavelength of maximum absorbance, electron affinity, ionization potential and photovoltaic parameters has been done in this work using density functional theory (DFT) and time dependent density functional theory (TD-DFT) methods. Among the studied dye molecules, maximum efficiency of 5.3% at JSC = 15 mA cm−2 is shown by the dye CB. As it is well known that the device's efficiency depends on photovoltaic parameters, these can be augmented by small variation in the geometry of dye as indicated by this study.\u0000 </div>","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"73 10","pages":"1636-1644"},"PeriodicalIF":2.0,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149177233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
