Towards effective Pd nanoparticles immobilization on NH2-MIL-53(Al) coated cellulose fiber: A stable and efficient catalyst for Suzuki reaction

Year: 2025

Type: article

Abstract: The modification of cotton fibers with sodium chloroacetate , followed by the incorporation of NH 2 -MIL-53(Al) through covalent bonding, has been successfully developed as a support for the immobilization of palladium nanoparticles . The integration of NH 2 -MIL-53(Al) into cellulose enhanced the specific surface area and introduced a significant number of amino groups and pore structures , which physically isolated the metal sites. Additionally, the introduction of nitrogen heteroatoms offers numerous anchoring points, effectively preventing the loss and aggregation of the metal species. Transmission electron microscopy (TEM) analysis demonstrated that palladium nanoparticles were uniformly distributed throughout the matrix, with an average particle size of 1.29 nm. The catalytic performance of this catalyst was evaluated in the Suzuki-Miyaura reaction, which facilitates the coupling of aryl halides with arylboronic acids in the presence of 0.006 mol% palladium species. Notably, the catalyst exhibited good reusability, maintaining its catalytic performance over four cycles without a significant loss of activity.
