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.
