The development of heterogeneous palladium-based catalysts and sustainable ligand-free catalytic systems remains a key focus in Suzuki coupling research, aiming to minimize environmental impact, enhance resource utilization, and advance the sustainability of chemical processes. In this study, Al₂O₃ precursors were synthesized via electrospinning, followed by calcination at varying temperatures to produce different crystalline forms of Al₂O₃. Pd/Al₂O₃-x catalysts were then prepared using an impregnation method. The structural properties of the synthesized catalysts were systematically characterized using SEM, TEM, XRD, XPS, BET, and FTIR. The results demonstrate that the catalysts exhibit a fibrous tubular morphology with uniform Pd dispersion, thereby increasing the number of active Pd nanoparticles. Notably, γ-Al₂O₃ exhibited stronger interactions with Pd compared to the other crystalline forms. The resulting material demonstrated exceptional catalytic performance in Suzuki coupling reactions, achieving a high turnover frequency (TOF = 3186.1 h^-1). The effects of reaction temperature, time, solvent, and base on catalytic efficiency were systematically investigated in this work. Moreover, the catalyst maintained stable activity over five reaction cycles, highlighting its excellent recyclability and reusability.</div></div>","PeriodicalId":374,"journal":{"name":"Journal of Organometallic Chemistry","volume":"1040 ","pages":"Article 123837"},"PeriodicalIF":2.1,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144926167","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}

This review article explores the green synthesis of Multi-Walled Carbon Nanotubes (MWCNTs) and their promising applications in dye degradation. Traditional synthesis methods of MWCNTs often involve hazardous chemicals and energy-intensive processes, prompting a shift towards greener alternatives. The green synthesis of MWCNTs employs eco-friendly routes, such as plant extracts, microbial synthesis, and biomolecule-assisted methods, aligning with the principles of green chemistry. This review systematically examines the various methodologies of green synthesis, highlighting the chemical and biological mechanisms that underpin these processes. Additionally, the characterization techniques used to evaluate the structural and functional attributes of green-synthesized MWCNTs are discussed in detail. The application section focuses on the adsorption mechanisms of dyes on MWCNTs, factors influencing degradation efficiency, and the comparative performance of green-synthesized MWCNTs against conventionally produced counterparts. Emphasis is placed on case studies that demonstrate the practical efficacy of these nanomaterials in removing dyes from aqueous solutions. Despite the potential benefits, challenges such as scalability, cost-effectiveness, and environmental impacts of large-scale production remain. This review underscores the necessity for ongoing research and development to overcome these barriers, thereby advancing the field of sustainable nanotechnology for environmental applications.

The catalytic system delivers high activity, achieving up to 94 % isolated yield of triphenylphosphane in a short time (2 h) under mild conditions (80 °C, KOAc, 2-MeTHF).
