One-step reaction has been developed to obtain Ag@Polyanilin (Ag@PANI) core-shell nano-structures. Aniline sulphate was oxidized by silver nitrate using solid-state polymerization method at room temperature. The structure and morphology of the core-shell were characterized by the Fourier transform infrared (FTIR) spectra, Ultraviolet-Visible (UV–Vis) absorption spectra, X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The XRD patterns displayed both the broad amorphous polymeric and sharp metallic peaks. The results from TEM and SEM images showed that the nano-composites have coreshell structures. The changes occurring in the structure of PANI are discussed on the basis of infrared and UV-Vis spectroscopy. The spectra revealed the formation of the nano-composites.

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