Immobilizing Pd nanoparticles on Fe3O4 @tris (hydroxymethyl) aminomethane MNPs as a novel catalyst for the synthesis of bis (pyrazolyl)methane derivatives

In this study, another approach for developing nanomaterials including Pd nanoparticles is reported. Fe3O4@THAM-Pd MNPs have been synthesized by a bottom-up strategy. Then, the structure of the nanocatalyst was completely confirmed by several techniques like BET, TEM, ICP-OES, FTIR, EDS, MAP, SEM, XRD, TGA/DTG, and VSM. Finally, the catalytic efficiency of the novel synthesized nanocatalyst was scrutinized in the synthesis of bis (pyrazolyl)methane derivatives. Furthermore, the recyclability and stability of Fe3O4@THAM-Pd MNPs were checked. The results showed that Fe3O4@THAM-Pd MNPs can use as a new and efficient heterogeneous catalyst. The stability of nanocatalyst can be due to the strong interaction of N-rich shells with Pd nanoparticles. (C) 2021 Elsevier B.V. All rights reserved.
