The hierarchically structured core-shell magnetic mesoporous silica nanospheres (Mag-MSNs) have attracted extensive attention, particularly in studies involving reliable preparations and diverse applications of the multifunctional nanomaterials in multi-disciplinary fields. Intriguingly, Mag-MSNs have been prepared with well-designed synthesis strategies and used as adsorbent materials, biomedicines, and in proteomics and catalysis due to their excellent magnetic responsiveness, enormous specific surface area and readiness for surface modifications. Through a carefully designed surface modification of Mag-MSNs, the performance and application prospects of the material are greatly improved. Typically, the introduction of various molecular matrices into the shell of Mag-MSNs facilitates the combination of surface modifications and magnetic separation technology. So far, as sustainable chemistry is concerned, it is important to recover the functionalized core-shell Mag-MSNs after the reaction and reuse them without losing activity. In this review, the design conceptions and the construction of core-shell Mag-MSNs are discussed. Furthermore, various surface modification approaches of core-shell Mag-MSNs are summarized, and recent applications of these functionalized nanomaterials in the fields of biomedicine, catalysis, proteomics and wastewater treatment are exemplified. 2 3 4 5 6 7 8

“…On the other side, high stirring speeds (i.e., 1200 rpm) yield spherical or irregular morphologies. The stirring speed has two main effects in the synthesis: (i) it alters the self-assembly of the template and (ii) it affects the diffusion of the reagents to the interface [17]. In the synthesis of wrinkled SiO 2 , high stirring speeds (around 900 rpm) are preferred to obtain a spherical morphology.…”

“…Hierarchically porous materials have the advantage that micro-and mesopores provide the size and shape selectivity for guest molecules, enhancing the host-guest interactions, whereas macropores favor the diffusion and accessibility of guest molecules [14]. The need for tailored porous materials for different applications has motivated the design of hierarchical meso/macroporous silica by different synthetic approaches [15]; most of them are based on the sol-gel chemistry at liquid interfaces using arrangements of amphiphilic molecules as templates [16][17][18]. Interesting examples of these materials are the so-called dendritic fibrous nanosilicas (DFNS) [19][20][21], such as KCC-1 spheres (KAUST Catalysis Center-1) that are potentially useful for solving problems in catalysis, photocatalysis, DNA adsorption, CO 2 capture, optical devices, and drug delivery [22].…”

Supporting a photocatalyst, such as titania nanoparticles (TiO 2 NPs), is a good strategy to improve its performance since it can facilitate the photocatalyst recovery from the aqueous media and provides a high surface area for pollutant adsorption. Among the several advanced functional materials used as TiO 2 NP support, the hierarchical meso/macroporous SiO 2 spheres not only show the advantages associated to its chemical nature but also the dendritic fibrous structure provides a porous network that offers many benefits to be exploited in optical and catalytic devices. In this chapter, different synthetic approaches to design hierarchical meso/macroporous silica and the strategies to support TiO 2 NPs regarding the photocatalytic performance of these materials are shown.

“…Indeed, the propylamine group is a sacrificial part of the template, while the silica skeleton behaves and is managed exactly as a hard template. It is worth noting that the PA is a commercially available reagent and the functionalization of silica is a well consolidated procedure employed for a plethora applications in separation a recognition techniques . Therefore, the scope of the paper is to present the development of an innovative synthesis for the preparation of a nitrogen doped carbon (NMC), the NMC chemical and electrochemical characterization and its employment as supercapacitor electrode material.…”

In this paper, nitrogen doped carbon materials with mesopores 4–8 nm‐wide and a high surface area of ca.1100 m2 g−1 were synthesized according to an innovative hard template method. Sucrose was used as carbon source and propylamine functionalized silica acted as both nitrogen source and templating agent. The novel doped carbons were compared with mesoporous carbons featuring similar texture properties (pore size and surface area) but obtained by the pyrolysis of sucrose or 1,10‐phenantholine and employing non‐functionalized silica as a templating agent. The interest of this investigation is to understand how doping occurs when a functionalized silica is employed, and whether the nitrogen doping remains a surface property or it is extended also to the bulk of the material, influencing the morphological and the electrical properties of the resulting carbon. X‐ray photoemission spectroscopy, elemental analysis, and EDX confirmed the doping action of the functionalized silica and the electrochemical characterization allowed to compare the different performances as supercapacitor materials.
