Title:  Magnetic Nanocatalysts for green chemistry: Synthesis and applications. A study from fresh to spent.

This PhD project deals with the synthesis characterization and applications of M-doped magnetite based nanocatalysts, where M stands for Cu, Pd, Ru, Cu-Ni, Ni-Sn. The proposed catalysts will be synthesized by an innovative microwave assisted hydrothermal method following the principles of Green Chemistry and will be properly characterized to assess magnetic properties (VSM) and to elucidate consequent structure-catalytic performance relationships in both oxidation and hydrogenation reactions concerning furfural, an outstanding renewable molecule with high industrial scope. Complete characterization of the spent catalysts is also programmed in order to get some insights on catalysts’ stability.
