Brief Review on Amino-Functionalized Mesoporous Silica Nanospheres
for Nanoreactors by Nanoengineering
Author(s): Feng Jinsuo*
For MSN Nanoengineering, mesoporous silica Nanospheres (MSNs) must be selectively functionalized. To create functionalized MSNs with externally attached amino groups, we have combined "surface-protected etching method" and "cationic surfactant assisted etching technique" in this study. The catalysts have high catalytic activity for the nitroaldol reaction between nitromethane and benzaldehyde thanks to the externally connected NH2 groups. These NH2-MSNs can also host gold nanoparticles, which have excellent catalytic activity for reducing 4-nitrophenol. It is conceivable that the synthesis technique created in this work might also be applied to nanoengineered MSNs, opening up possibilities for the construction of Nanoreactors. .. View more»
