Although graphitic carbon nitride (C3N4) possesses both visible-light responsiveness and a moderate band structure, its catalytic efficiency is drastically hampered by the rapid recombination of photoexcited carriers and inevitable hydrogen–oxygen reverse reactions. To overcome these critical bottlenecks, a Cr2O3/Pt/C3N4 catalyst was successfully constructed via in situ photodeposition. Notably, the as-prepared Cr2O3/Pt/C3N4 catalyst enables efficient visible-light-driven one-step excitation OWS, exhibiting a catalytic activity 4 times superior to that of pristine Pt/C3N4. Combining density functional theory (DFT) calculations and structural characterization, it was found that the in situ deposited Cr2O3 protective layer on the cocatalyst effectively modulates the electronic structure and adsorption energy of Pt, thereby inhibiting the oxygen–hydrogen recombination reaction and enabling stable and efficient hydrogen production. This work thereby lays a theoretical foundation and offers technical pathways for the design strategy and application exploration of highly efficient C3N4-based photocatalysts.","PeriodicalId":95,"journal":{"name":"New Journal of Chemistry","volume":" 24","pages":" 10229-10235"},"PeriodicalIF":2.6,"publicationDate":"2026-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148285362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite extensive investigation conducted on the photocatalytic properties of rGO/metal oxide composites, trimetallic heterojunction systems that can facilitate directional charge carriers are still underdeveloped. In this study, a trimetallic CdO–TiO2–ZrO2 oxide (CTZ) photocatalyst supported on rGO, denoted as CTZ/rGO, was successfully synthesised via a sol–gel method, which facilitated interfacial charge separation. This enhanced the photocatalytic and antibacterial performance. The CTZ/rGO composite showed better degradation efficiency than the pure CTZ system, i.e. 87.08% for Alizarin red and 86.96% for Nile blue, with 60 minutes of exposure time under UV light illumination. The apparent rate constant increased up to 0.0338 and 0.0337 min−1, respectively, indicating enhanced reaction kinetics. The reduction of the band gap to 2.11 eV and the enhancement of the electron transport across the interface indicated that the charge transport mediated by rGO supresses electron–hole recombination. It also retained ∼80% degradation efficiency after five cycles. It exhibited significant antibacterial activity towards both Gram-positive and Gram-negative bacteria. These results demonstrate the impact of heterojunction engineering and the integration of charge carriers with a conductive carbon substrate. The results also demonstrate the feasibility of a multifunctional material for environmental remediation on a large scale.","PeriodicalId":95,"journal":{"name":"New Journal of Chemistry","volume":" 24","pages":" 10278-10292"},"PeriodicalIF":2.6,"publicationDate":"2026-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148285311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, developing stable, efficient catalysts to simultaneously improve cyclohexane conversion and cyclohexene selectivity remains a critical challenge. Herein, porous single-crystal vanadium oxide was synthesized via a facile route as an electrode catalyst. A proton-conducting solid oxide electrolyzer (p-SOE) was constructed using Sn0.9In0.1P2O7 as the electrolyte owing to its high proton conductivity and low activation energy. Electrochemically driven cyclohexane dehydrogenation toward cyclohexene was investigated. At 600 °C and 0.8 V, the system achieves a cyclohexane conversion of 97% and a cyclohexene selectivity of nearly 99.7%, together with excellent stability.

Carbon dots (CDs) are promising drug delivery systems because of their biocompatibility, low toxicity, and better stability for improved cellular uptake. The synthesis of drug-loaded CDs using a greener approach and their applications in biology are attracting considerable attention nowadays. Here, we report an eco-friendly method for the synthesis of CDs and their application to carry a hydrophobic drug, curcumin, in live cells. In addition, the molecular interactions of curcumin-loaded CDs (C-CDs) with partially unfolded BSA were demonstrated by steady-state and time-resolved fluorescence resonance energy transfer (FRET). The real-time diffusion dynamics and cellular uptake kinetics of C-CDs were studied by raster image correlation spectroscopy (RICS) and live-cell imaging, respectively. The antibacterial efficacy and cytotoxicity of C-CDs were determined via an MTT-based assay and minimum inhibitory concentration (MIC) analysis. Our findings provide a greater insight into the integrated application of C-CDs for drug delivery and bioimaging.","PeriodicalId":95,"journal":{"name":"New Journal of Chemistry","volume":" 24","pages":" 10313-10329"},"PeriodicalIF":2.6,"publicationDate":"2026-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148285369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultrasonic treatment enabled nanoscale dispersion, yielding well-crystallized CuMnO2 nanowires with a crednerite structure and hexagonal g-C3N4 nanosheets. The cation–π interaction, mediated by Cu–N<img>C linkages, facilitates dynamic electron transfer from the conjugated π-system of g-C3N4 to the metal centers. This electron redistribution results in increased ratios of Cu+ and Mn3+, reduced charge transfer resistance, and enhanced oxygen mobility. The resulting electron-rich metal active sites promote ozone adsorption and its subsequent decomposition into *O2 and *O species, which further generates ˙O2− radicals. With an exceptionally low activation energy of 19.84 kJ mol−1, this catalyst significantly improves ozone utilization efficiency and exhibits excellent catalytic activity in water treatment, holding broader significance for sustainable chemistry applications.","PeriodicalId":95,"journal":{"name":"New Journal of Chemistry","volume":" 22","pages":" 9531-9544"},"PeriodicalIF":2.5,"publicationDate":"2026-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148193757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ambient-temperature catalytic oxidation offers an effective alternative, decomposing HCHO into CO2 using high performance transition metal oxides. A new class of metal–organic framework (MOF)-derived monometallic and bimetallic oxides and supported catalysts with different carriers were synthesized by the hydrothermal method and investigated in this study. 1.0 g of catalyst powder was dispersed uniformly on a Petri dish (Φ = 90 mm) and the initial concentration of HCHO was regulated to 1.0 ± 0.5 mg m−3. The reaction temperature was set to ambient temperature (25 ± 5 °C), and the HCHO concentration measurements were performed in triplicate every 12 h. Among them, MnCe-MOF-derived oxides displayed a high degradation rate (96.3%) at 48 h, with notable stability attributed to the synergistic redox cycling of Ce4+/Ce3+ and Mn3+/Mn4+, which generated abundant reactive oxygen species (ROS, O2− and ˙OH), along with their excellent hydrophobicity. Electron paramagnetic resonance (EPR) analysis revealed that oxygen-deficient sites facilitate the complete oxidation of HCHO. Among the supported catalysts, 20 wt%MnCe-MOFs/ZSM-5 also exhibited a high oxidation activity (93.4%) ascribed to abundant active components of MnCe-MOFs, surface weak acid sites, high surface areas, and abundant oxygen vacancies, indicating high stability for HCHO oxidation.","PeriodicalId":95,"journal":{"name":"New Journal of Chemistry","volume":" 25","pages":" 10662-10674"},"PeriodicalIF":2.6,"publicationDate":"2026-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148336710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Incorporating metallophthalocyanines (MPcs) as building units can further enhance POP functionality, introducing conjugated π-systems and metal active sites. This is particularly attractive for photo-driven CO2 cycloaddition, a sustainable route to convert CO2 and epoxides into cyclic carbonates. However, conventional MPc-based POPs often suffer from limited functional diversity and structural rigidity. Their synthesis typically relies on harsh solvothermal/ionothermal conditions, which risk degrading the MPc structure and entail high energy costs. To address these challenges, we report a function-oriented design coupled with a mild synthetic strategy. Using 4-dimethylaminopyridine (DMAP) as a dual-purpose reagent (reaction medium and catalyst), we efficiently constructed pyrazine-linked MPc-POPs (PyCoPc-POPs) by the polymerization of 2,3,5,6-pyrazinetetracarbonitrile (TCNP) in the presence of Co atoms. The pyrazine linker not only enhances framework polarity and CO2 uptake but also provides Lewis basic sites that synergize with CoPc metal centers for catalysis. Furthermore, to improve charge separation and transport—critical for photocatalysis—we integrated reduced graphene oxide (rGO) via an in-situ compositing approach, ensuring intimate contact between the components. The resulting PyCoPc@rGO hybrid exhibited outstanding performance in the photo-driven CO2 cycloaddition, achieving 97.5% epichlorohydrin (ECH) conversion and exceeding 99% carbonate selectivity under mild conditions. This work demonstrates the versatility of our mild synthetic method and offers a new design paradigm for high-performance photocatalytic materials.","PeriodicalId":95,"journal":{"name":"New Journal of Chemistry","volume":" 23","pages":" 9777-9785"},"PeriodicalIF":2.5,"publicationDate":"2026-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148247631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a nanocellulose/SiO2 composite aerogel with high oil adsorption capacity and good thermal insulation performance was synthesized via one-pot synthesis using active silanol, methyltrimethoxysilane (MTMS), and hexadecyltrimethoxysilane (HDTMS). The effects of preparation conditions (the nanocellulose concentration, tert-butyl alcohol content, active silanol content, MTMS content, and HDTMS content) on its oil adsorption performance were explored. The results indicate that the nanocellulose/SiO2 composite aerogel exhibited a three-dimensional porous structure with improved hydrophobicity (contact angle up to 149.2°), resulting in excellent oil adsorption capacity (up to 131.2 g g−1) and thermal stability (no significant weight loss below 320 °C). Furthermore, the as-prepared aerogel showed superior thermal insulation performance, as reflected by a low surface temperature (65.7 °C) compared to unmodified nanocellulose (84.3 °C) when exposed to a 120 °C heat source.
