Abstract. This study aims to investigate the application of multi-core shell nanoparticles in heterogeneous Fenton processes for efficient removal of specific nitrophenols (2 and 4-nitrophenol) from contaminated wastewater. The synthesis of superparamagnetic magnetite (Fe3O4) was achieved through solution combustion synthesis (SCS) using a citric acid and iron nitrate solution. The mFe3O4@C catalyst was obtained via an adapted Stöber procedure. The material was characterized to identify specific chemical compositions related to the formation of the multi-core shell desired architecture. The carboncoated catalyst exhibited superior performance compared to the bare core catalyst, leading to notable increases in the removal of 2-NP and 4-NP. Moreover, the decomposition of H2O2 was significantly enhanced, indicating the system's potential in efficiently breaking down hazardous compounds. The findings of this study highlight the tremendous potential of the system as a highly effective and viable alternative for the efficient cleansing of contaminated streams polluted with 2-nitrophenol and 4nitrophenol.
