Abstract

Recently, nanostructured NiFe₂O₄ magnetic particles have emerged effective oxidizing and reducing agents when doped with ions like Pd, Au, Pt etc. Specifically, NiFe₂O₄-Pd magnetically recyclable composites have been recently reported as highly effective catalysts for reduction reactions in liquid phase. In this context, the present report proposes a cast effective synthesis of NiFe₂O₄/Pd composites via sol-gel auto-combustion route in order to investigate the effect of Pd (0 - 10%) contents in NiFe₂O₄ on the structural, morphological, room temperature (RT) and low temperature (LT) magnetic properties.
