These salts were employed as N-heterocyclic carbene (NHC) precursors and reacted with Pd(OAc)₂ to afford a series of [PdCl₂(NHC)₂]-type palladium(II) NHC complexes. The catalytic activity of the synthesized complexes were evaluated in the direct C–H arylation of thiazole-derived heteroaromatic compounds. Two different thiazole derivatives, namely 2-<i>n</i>-propylthiazole and 4,5-dimethylthiazole, were selected as substrates, and their reactivity with aryl bromides bearing different electronic properties was systematically investigated. The arylation yields were found to vary significantly depending on both the substitution pattern of the thiazole ring and the nature of the aryl halides. Notably, aryl bromides containing electron-withdrawing groups facilitated the oxidative addition step and afforded higher yields, whereas those bearing electron-donating groups resulted in lower reactivity. These findings suggest that the catalytic performance of the Pd–NHC complexes is influenced not only by the metal center but also by the ligand environment and the electronic characteristics of the substrates involved. In conclusion, this study demonstrates that structurally tunable Pd–NHC complexes can serve as effective homogeneous catalysts for the selective and efficient C–H functionalization of thiazole-based heteroaromatic compounds. The results contribute to the ongoing development of versatile catalyst systems for direct functionalization of electron-rich heterocycles, providing a foundation for future investigations in this area.</p></div>","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"69 19","pages":"2708 - 2717"},"PeriodicalIF":3.7,"publicationDate":"2026-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11244-026-02300-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

EDX analysis verified the presence of all the elements within the ZnSe/NiFe₂O₄ composite, which was further confirmed by the XPS studies. Tauc plot analysis revealed a direct band gap of 1.69 eV for the composite. Further, VSM analysis revaled that the ZnSe/NiFe₂O₄ nanocomposite exhibits a saturation magnetization (Ms) of 12.63 emu g^− 1, a coercive field (Hc) of 141.99 Oe, and a remanent magnetization (Mr) of 2.44 emu g^− 1. Additionally, it was found that the modification of the band gap and reduction in charge recombination result in the enhanced visible-light activity of the ZnSe/NiFe₂O₄ composite (reduced PL emission and increased MB dye degradation efficiency of 93% as compared to the pure ZnSe which showed 54.6% of degradation efficiency). Also, the composite has a good magnetic recoverability and operational stability with 87% of degradation efficiency remaining after four reuse cycles, showing a low level of deactivation and good structural integrity. The improved photocatalytic performance, the high efficiency of charge separation, magnetic separation, and long-term reusability of the ZnSe/NiFe₂O₄ system are the features that demonstrate the high practical importance and novelty of ZnSe/NiFe₂O₄ in contrast to traditional single-component photocatalysts. Further, kinetic studies revealed that the degradation followed pseudo-first-order kinetics with a rate constant of 0.02053 min^− 1. The underlying photocatalytic mechanism was also investigated through VB-XPS analysis, Tauc plot analysis, and scavenger studies.

ICP-OES analysis confirmed boron contents of 200.7 ppm and 651.7 ppm for BGO-5 and BGO-55, respectively.

When integrated into soil-based single sugar beet PMFC systems, BGO-55 significantly enhanced power density in both anode (0.936 mW m⁻²) and cathode-modified (0.967 mW m⁻²) configurations following whey supplementation. The improved performance is attributed to the synergistic interaction between increased boron content, defect-mediated electronic modulation, and enhanced ORR kinetics under substrate-enriched conditions.

In this experimental study, La₂O₂CO₃ and La₂O₃ nanowire catalysts were synthesized hydrothermally using different alkaline precipitants under identical conditions. Structural and surface analyses (XRD, FE-SEM, BET) demonstrate the decisive role of the precipitant in controlling phase composition, morphology, and surface area. The ammonia-derived La₂O₂CO₃ catalyst (A-500) demonstrated stable OCM activity at temperatures as high as 350 °C, yielding a C₂₊ yield of 12.3%. This finding indicates that the reported onset temperature for OCM is among the lowest documented to date. As the temperature increased, the A-500 demonstrated a maximum C₂₊ yield of 13.1% at 500 °C, exhibiting suppressed COx formation. Over the duration of 50 h, the system maintained approximately 31% CH₄ conversion and 44% C₂₊ selectivity without any discernible deactivation. The results suggest that OCM performance is governed by a coupled structural parameter space in which crystallite size, morphology, and surface area act synergistically to determine catalytic efficiency. Consequently, the integration of hydrothermal synthesis with a judicious selection of precipitant agents has yielded La-based catalysts that exhibit remarkably low-temperature activity and prolonged durability. This approach provides a set of pragmatic design principles for the development of catalysts in the context of low-temperature OCM.</p></div>","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"69 19","pages":"2693 - 2707"},"PeriodicalIF":3.7,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11244-026-02288-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
