Heterogeneous Fenton Catalyst

We report a novel FeS2 loaded large SiO2 sphere (diameter of 3 cm) via double immobilization with (3-mercaptopropyl)trimethoxysilane (KH590) as a highly efficient, stable, and tweezers-recoverable heterogeneous Fenton-like catalyst (FeS2/KH590/SiO2@KH590). Notably, as-prepared composite catalyst exhibits a significant recycling improvement (10 runs) over free FeS2 powder (3 runs). The outstanding recyclability and stability of FeS2/KH590/SiO2@KH590 can be attributed to the passivation of FeS2 nanoparticles on SiO2 surface by KH590 and subsequent prevention of Fe2+ leaching. Overall, our work provides a new avenue towards fabricating composite Fenton-like catalyst with high stability, enhanced recyclability and the advantage of easy separation.

High dispersion of a large amount of Fe2+-rich FeOx and unblocked pore channels of catalysts obtained by physical-vapor-infiltration facilitate the Fenton reaction.
