Wei L, Shi D, Zhou Z, Ye P, Wang J, Zhao J, Liu L, Chen C, Zhang Y - Nanoscale Res Lett (2012)

Bottom Line: Mesoporous silica nanoparticles (MSNs) containing vinyl-, propyl-, isobutyl- and phenyl functionalized monolayers were reported.These functionalized MSNs were prepared via molecular self-assembly of organosilanes on the mesoporous supports.The relative surface coverage of the organic monolayers can reach up to 100% (about 5.06 silanes/nm.

Figure 2: The TEM of MSN (a), Vi-SAM-MSNs (b), Pr-SAM-MSNs (c), Is-SAM-MSNs (d), and Ph-SAM-MSNs (e).

Mentions: To synthesize the SAM-MSNs, the MSNs were first prepared. MSNs were synthesized in CTAB/OH, TEOS, and mesitylene solution, which have been reported previously [32,33]. As shown in the Figure 2, MSNs have a particle diameter of 100 to 200 nm and composed of ordered hexagonal array of mesoporous channels. The nitrogen surface sorption analysis of MSNs gave the BET surface area of 1,095 m2/g−1 and the pore size of 6.5 nm.
