MnFe 2 O 4 nanoparticles, an important member of nanostructured transition metal oxides, also known as spinel ferrites, find wide use in many applications, especially medicine and catalysis, due to their fascinating properties. In this research article, MnFe 2 O 4 and MnFe 2 O 4 supported Pd0 nanoparticles were primarily prepared by solvothermal and impregnation/reduction methods, respectively. After the structural and morphological examination of the MnFe 2 O 4 decorated Pd0 nanoparticles (Pd@MnFe 2 O 4), their catalytic activity was tested in the release of hydrogen from the methanolysis of hydrazine-borane. The morphological characterizations of Pd@MnFe 2 O 4 catalyst show that Pd0 nanoparticles were successfully decorated (average particle size ∼2.83 nm) on the flower-like MnFe 2 O 4 spinel ferrite nanoparticles. The Pd@MnFe 2 O 4 catalyst presented high catalytic performance in the H 2 production via the methanolysis of hydrazine-borane, and the turn-over frequency value at 298 K was 47.2 min−1, which is the highest catalytic systems in the literature for this purpose. The Pd@MnFe 2 O 4 catalyst displaying good activity in ten consecutive catalytic runs can be considered a good heterogeneous catalyst for the hydrogen production from the methanolysis of hydrazine-borane. [Display omitted] • MnFe 2 O 4 supported Pd0 NPs in were prepared by impregnation/reduction technique. • MnFe 2 O 4 supported Pd0 NPs were identified by advanced techniques. • MnFe 2 O 4 supported Pd0 NPs were tested as catalyst for the methanolysis of HB. • Catalytic activity of the catalyst is 47.2 min−1 for HB methanolysis at 298 K. • MnFe 2 O 4 supported Pd0 NPs were recyclable and could be reused for at least ten runs.
