“…At the same time, for the volume effect of isobutyl group, the outer part of the nanospheres could not form a highly condensed SiO 2 network, and then turned fluffy. 31 This characteristic could be more clearly observed by the magnification of one of the nanospheres (Fig. 1c).…”

“…The post-etching with water showed a large etching effect on the inner part than of the shell for the density difference, so the interior void was created. [28][29][30][31] With a similar two-step route, mesoporous hollow silica spheres have also been successfully prepared with a coating of mesoporous silica shell on the surface of the inner sphere before etching the inner part with aqueous Na 2 CO 3 . In that report, it was believed that the structure difference led to the core to be etched faster than the shell.…”

A series of hydrophobic hollow silica nanospheres with high specific surface areas and porous shells were successfully prepared through combination of a one-step reverse-phase microemulsion route and a simple post selective etching method. These materials owned porous shells and high specific surface areas, which were generated in the etching process. The distribution difference of organic groups among the solid nanosphere was innovatively utilized to create a different etching rate between the surface and the inner part of the solid silica nanosphere. After etching, the organic groups are still present on the surface which together with the rough surface give it hydrophobic properties and the contact angles can reach 150u. The reported materials showed good performance in the removal of 4-NP in water.

“…Among the silica fibers, spheres, rods and nanoparticles, the hollow nanospheres are very attractive, given that the hollow interior can encapsulate the guest molecules for wide application potentials [19][20][21][22][23][24][25][26][27][28]. The modification of the shell of the hollow nanospheres may further expand the application potentials of the hollow nanospheres [29][30][31][32][33][34][35].…”

a b s t r a c tIron-substituted silicas with hollow nanospherical morphology and cage-like mesostructure have been synthesized using triblock copolymer F127 as surfactant and tetramethoxysilane (TMOS) as silica source with no necessary addition of mineral acids. Iron-functionalized hollow nanospheres were obtained using Fe(acac) 3 as iron source. When Fe(NO 3 ) 3 was employed as iron source, iron-containing cage-like FDU-12 mesostructure and hollow nanospheres were formed with Fe/Si molar ratio lower than 0.008 and higher than 0.015, respectively. The formation of hollow spheres at high Fe/Si ratio can be regarded as gradually dissociation of nanocages from Fe-FDU-12. The structure of the iron centers was determined by spectroscopic methods (UV-vis and UV-Raman measurements) and by elemental analyses. The facile structural evolution between cage-like and nanospherical structures may be helpful for further understanding the formation mechanism of mesoporous silicas.
