The swelling behavior of crosslinked poly(ionic liquid)s (PILs) was systematically investigated, and PILs-0.8 (with 0.8 mol% DVB) exhibited the highest swelling capacity in polar solvents. The optimized composite, PILs/PCN-0.8-50 (50wt% PCN), demonstrated superior photocatalytic activity in the aerobic oxidative coupling of benzylamines under visible light irradiation, achieving 98% conversion within 9 h in DMF. Radical trapping experiments revealed that photogenerated electrons (e^-), superoxide radicals (‧O₂^-), and holes (h⁺) are the primary active species. The enhanced performance is attributed to the synergistic effect between the electron-rich PCN and the ionic conductive PILs, which facilitate charge separation and substrate enrichment. This work provides a facile strategy for designing polymer-semiconductor hybrid photocatalysts with improved efficiency and recyclability.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"156 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148782395","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}

The concentric graphitic layered structure of the catalyst is confirmed by HR-TEM images, and the mesoporous texture is evidenced by the nitrogen adsorption-desorption isotherms. The electrochemical evaluation of the catalyst in the alkaline medium gives a limiting current density of – 4.62 mA cm^− 2, which is on par with the current density recorded for commercial Pt/C. CoNCNO exhibits a favourable onset potential (0.91 V vs. RHE) and half-wave potential (0.79 V vs. RHE), along with the calculated electron number of 3.85, supporting its remarkable ORR catalytic activity. Moreover, the catalyst surpasses commercial Pt/C in stability in 0.1 M KOH, retaining 96% of its initial activity after 10,000 s.

To investigate the relationship between the preparation process and performance of CuCN-supported palladium nanoparticles, a light-induced synthesis method was employed to replace the traditional high-temperature thermal reduction process, enabling the controlled loading of palladium nanoparticles onto CuCN. A Cu- and N-co-doped carbon-supported palladium nanocatalyst (Pd/CuCN-M) was prepared, and the effects of optimal illumination conditions and reducer types on the catalyst were explored. The results show that the Cu- and N-co-doped carbon-supported palladium nanocatalyst, designated Pd/CuCN-M1, prepared using methanol as the reducing agent and irradiated with near-ultraviolet light at 395 nm, exhibits high catalytic activity and stability. The rate constant for the reduction of p-nitrophenol (4-NP) reached 2.1 min⁻¹, and the conversion rate remained at 90.2% after five cycles of stability testing.

Molybdenum disulfide (MoS₂) has been identified as a low-cost catalyst for photocatalytic hydrogen evolution; however, its practical application remains constrained by inherent drawbacks, including basal-plane inertness, poor electrical conductivity, and severe photogenerated carrier recombination. In this work, a series of flower-like MoS₂/CoP S‑scheme heterojunctions with varying molar ratios were synthesized via a hydrothermal method followed by a high‑temperature phosphorization process. Characterization results reveal that the introduction of CoP effectively refines the microstructural morphology, enhances the specific surface area, and increases the number of active sites. Meanwhile, the built‑in electric field established at the heterojunction interface facilitates efficient charge migration along the S‑scheme pathway, thereby extending the visible‑light response range and suppressing carrier recombination. When the molar ratio of MoS₂ to CoP was 1.0, the resulting composite exhibited the optimal photocatalytic hydrogen‑evolution performance, achieving a hydrogen production rate 3.43 times that of pristine MoS₂, while its catalytic activity remained stable after cyclic tests. This study demonstrates that constructing S‑scheme heterojunctions between transition‑metal sulfides and phosphides constitutes an effective strategy for modifying MoS₂‑based photocatalysts. Furthermore, it provides a viable reference for the development of low‑cost, high‑performance noble‑metal‑free photocatalysts for sacrificial‑agent‑assisted photocatalytic hydrogen production.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"156 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148751809","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}

The synthesized catalyst was characterized by X-ray diffraction (XRD), Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR), Brunauer–Emmett–Teller and Barrett–Joyner–Halenda (BET-BJH), scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDX), Hammett indicator analysis, and benzoic acid titration, confirming the formation of mesoporous CaO-NPs with an estimated crystallite size of 47.4 nm and a BET surface area of 16.0 m² g^− 1. Process optimization was performed using response surface methodology (RSM) via a central composite design (CCD), yielding a fatty acid methyl ester (FAME) yield of 97.40% under the optimal conditions of 137.0 min, 64.2 °C, and 2.6 wt% catalyst loading. Kinetic modeling in the range of 50–70 °C using nonlinear regression revealed that the pseudo-first-order model provided the best statistical fit to the experimental data, while generalized-order fitting yielded an average reaction order close to unity. The Arrhenius activation energy was 32.56 kJ mol-¹, whereas the activation thermodynamic parameters (ΔH^‡ = 29.80 kJ mol^− 1, ΔS^‡ = -0.22 kJ mol^− 1 K^− 1, and ΔG^‡ = 101.21-105.63 kJ mol^− 1) indicated the endothermic and non-spontaneous transition state formation. A preliminary mechanistic assessment suggested statistical consistency with an Eley-Rideal-type pathway. Furthermore, the catalyst exhibited good reusability, maintaining a FAME yield above 82% over 5 consecutive cycles.
