Abstract

Compared to epoxides, converting carbon dioxide (CO2) to cyclic carbonates is proposed as the most appropriate way to synthesize C1 building blocks. In this study, a Pd(II) Schiff base complex is fixed on FeNi3/DFNS nanoparticles and then reacted with melamine to provide a recoverable magnetic heterogeneous nanocomposite of FeNi3/DFNS/salen/Pd(II). It was determined that the FeNi3/DFNS nanoparticles are an appropriate catalyst for the oxidation carboxylation of styrenes with CO2 in a one-step reaction. The FeNi3/DFNS nanoparticles were characterized via XPS, FTIR, EDX, FE-SEM, XRD, TGA, TEM, IC, VSM and BET analyses. The important benefits of this catalyst are its easy work-up, low cost and high efficiency.
