Iron Based Core-Shell Structures as Versatile Materials: Magnetic Support and Solid Catalyst

Core-shell materials are promising functional for fundamental research and industrial application, as their properties can be adapted specific applications. In particular, particles featuring iron or oxide core material relevant since they combine magnetic catalytic properties. The addition of an SiO2 shell around the introduces additional design aspects, such a pore structure surface functionalization. Herein, we describe synthesis application iron-based core-shell nanoparticles two different fields that is heterogeneous catalysis water purification. were characterized by transmission electron microscopy, well N2-physisorption, X-ray diffraction, vibrating-sample magnetometer measurements in order to correlate with performance target Investigations these CO2 hydrogenation purification show versatility applicability after suitable individual functionalization precursor. For magnetically separable particles, surface-functionalized ionic liquid bind pollutants selectively. requires no functionalization, it provides as-made state. gas reactions, SiO2-stabilized reductively functionalized provide catalytically active metallic sites. Therefore, Fe@SiO2 nanostructures shown platform various
