摘要

Enhancing the dispersion and anchoring strength of metal nanoparticles on biopolymers and 2-D layered supports is crucial for catalytic applications. This study explores the catalytic performance of Pd and Boron nitride(BN) nanosheets dispersed on a chitosan matrix. Boron nitride, chosen for its two-dimensional layered structure that enables strong metal interaction, was prepared via the liquid-phase exfoliation method and functionalized with a hydroxyl group to enhance dispersibility. A chitosan-supported Pd/BN nanocomposite was synthesized via an in situ chemical reduction method. Various Characterization techniques, including XRD, FTIR, Raman, UV–Vis, XPS, SAED, SEM, and TEM, confirmed the successful formation of the composite and Pd/BN anchoring on the chitosan support. The composite effectively catalyzed the reduction of 4-Nitrophenol to 4-Aminophenol within 30 min at room temperature, demonstrating enhanced catalytic activity of the composite.
