“…[14][15][16] Compared with simple yolk-shell nanoparticles, megranatelike nanoparticles own multiple cores. [17][18][19][20] They can afford more exposed active sites and show better catalytic activities. [21][22][23][24] Therefore, megranate-like nanoparticles with many catalytically active cores have presented promising applications in catalytic field as nanoreactors.…”

Megranate-like nanoparticles possess a unique structure that is composed of multiple cores and shells, which is different from simple yolk-shell nanoparticles. Megranate-like nanoparticles can combine the properties of each component and be used as nanoreactors. This study describes the preparation of bifunctional megranate-like nanoreactors, consisting of multiple metal cores and thiol modified mesoporous SiO2 shells. Different metal nanoparticles (Pd, Pt, Au) can be incorporated into the structure as cores, and the thiol group in the shells can be oxidized to acidic -SO3H. The megranate-like nanoparticles show good bifunctional catalytic properties and recyclability in a cascade catalytic reaction for the desired benzimidazole derivative. Moreover, the individual components of the megranate-like nanoparticles also show good catalytic activities in the hydrogenation reduction of nitro-aromatics and the deprotection reaction of benzaldehyde dimethyl acetal.

“…The first three articles deal with mathematical models for polymerization in heterogeneous media, and the simulated results are discussed in light of the experimental data. Luciani and Choi proposed a kinetic model for the formation of “pomegranate‐like particles” during suspension polymerization. The thermodynamic aspects of phase separation were included in their kinetic model.…”

“…Composite nanomaterials with well-defined structures that combine the characteristics of each component or achieve cooperatively enhanced performance have been extensively investigated [2,7]. In particular, core-shell structured nanomaterials have been extensively explored, and various morphologies, such as pomegranate [9][10][11], raspberry [12,13], yolk shell (or rattle-type) [4,[14][15][16][17][18], cauliflower [19,20] and sandwich [15,21]-like forms, have been revealed.…”

Different core-shell structured silica-titania (SiO 2-TiO 2) nanocomposites were successfully synthesised in two successive stages. In the first stage, the core was synthesised by preparing poly[oligo(ethylene glycol)monomethyl ether methacrylate] (POEOMA) on the modified surface of silica nanoparticles (SiO 2-POEOMA). In the second stage, the shell was formed by depositing or coating tetrabutyl titanate (TBT) with SiO 2-polymer to obtain cauliflower-like, cauliflower-pomegranate-like and pomegranate-like SiO 2-POEOMA-TiO 2 microspheres; the weight ratio of added SiO 2-POEOMA to TBT (1:0.146, 0.293 and 0.439) was then adjusted. Later, the polymer layer was removed to obtain the cauliflower-like, cauliflower-pomegranate-like and pomegranate-like core-shell structured SiO 2-TiO 2 microspheres (CMs, CPMs and PMs). X-ray diffraction results showed that the TiO 2 shell was a pure anatase phase. SiO 2-TiO 2 microspheres were also characterised by N 2 adsorption-desorption; the results showed that a pore structure was found in the porous shell. Extensive porosity was generated in the shell because POEOMA was used as a template and pore-forming agent; the structure of CMs, CPMs and PMs remained almost unchanged. These results also showed that pore volumes and specific surface areas of the final products derived from N 2 sorption decreased as the content of TBT increased. PMs with the highest content of TiO 2 showed the most efficient photocatalytic activity.
