Facile Synthesis of Magnetic Bentonite–Chitosan–Pd Nanocomposite: As a Recoverable Nanocatalyst for Reduction of Nitroarenes and Suzuki–Miyaura Reaction

Abstract

In this study, a facile approach successfully developed a new Pd nanocatalyst supported by magnetic bentonite–chitosan with easy accessibility to active sites and a high surface area. The synthesized Fe3O4/Bentonite/Chitosan/Pd nanocatalyst indicated a good catalytic activity for the reduction of nitroarene compounds and the Suzuki–Miyaura reaction in water at mild conditions. Importantly, the Fe3O4/Bentonite/Chitosan/Pd nanocatalyst was readily recovered and reused for at least five cycles in both reactions; therefore, proving its good stability. These results demonstrate that magnetic bentonite is suitable to support, and it can be utilized for various catalytic systems as support.
