Core Shell Structure

Hierarchical porous titanate nanotube hollow microspheres were synthesized through a template-hydrothermal method. First, SiO2@TiO2 core-shell structure was synthesized, and then titanate nanotube hollow sphere was prepared via a simple hydrothermal method. The dimension of the cavity could be simply tuned by controlling the size of SiO2 spheres. These hollow microspheres exhibited a unique porous structure, in which the nanotube hollow microsphere had a two-fold storage system including the cavity of the hollow sphere and the nanotube capability. Further, the microsphere demonstrated an improved controlled releasing performance that the cavity was capable of giving a fast releasing, while the channel of the nanotube showed a slow releasing property. This facile template-hydrothermal method could be a generally strategy to prepare hollow nanostructures.

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.
