“…The nitrogen adsorption and desorption isotherms of unmodified-and modified-NAMs after calcination are classified as a type-IV isotherm, which is often observed in CTABtemplated mesoporous silica materials, 25,26 and are similar to those we reported previously. 7 The structural parameters analyzed by the isotherms are summarized in Table 1.…”

The apparent diffusion coefficients of tris(2,2′-bipyridyl)ruthenium ([Ru(bpy3)] 2+ ) are estimated in silica-nanochannels which are assembled inside columnar alumina pores in an anodic alumina membrane, and are modified with alkylsilanes such as trimethylchlorosilane (C1), butyldimethylchlorosilane (C4), and dodecyldimethylchlorosilane (C12). The estimation is performed by observing the lag-time, which is defined as the time required for [Ru(bpy)3] 2+ to diffuse through alkylsilane-modified silica-nanochannels in the alumina membrane. When ethanol is used as a solvent, the apparent diffusion coefficients of [Ru(bpy)3] 2+ are estimated as 2.1 × 10 -10 and 3.2 × 10 -10 cm 2 s -1 in the C1-and C4-modified silica-nanochannels, respectively. These values are about 10 4 times smaller than that obtained in bulk ethanol. Based on the experimental results on the solvent dependency of the lag-time, the hydrogen-bonding interaction between ethanol molecules is considered to be stronger in the C1-and C4-modified silica-nanochannels than in bulk ethanol, and the hydrogen-bonding interaction plays a critical role for the slow diffusivity in those nanochannels. In contrast, the apparent diffusion coefficient in the C12-modified silica-nanochannel is at least two orders of magnitude larger than those in the C1-and C4-modified silica-nanochannels. This relatively fast diffusion is most likely explained by the presence of a long alkyl chain of C12, which reduces a hindrance effect that is originates in the hydrogen-bonding interaction.

“…There was a slight decrease in the d 100 value when the template was removed by calcination, i.e., from 3.59 (as-synthesized MCM-41) to 3.26 nm (MCM-41), indicating shrinkage of about 9.2%. Assuming a hexagonal symmetry, the pore diameter of MCM-41 was estimated to be 2.8 nm from the repeating distance a 0 (3.76 nm) between two pore centers, calculated by a 0 = 2/ √ 3 d 100 , and the wall thickness of about 1.0 nm [4,5,[31][32][33].…”

A novel technique was developed to prepare highly pure heteropoly acid (HPA) nanocrystals inside mesoporous SBA-15 by the imprisoned reaction of HPA etherate and water, which was utilized as a main driving force for the transportation of building-blocks. The transmission electron microscopy, X-ray diffraction, FT-IR spectrum and NMR characterizations unambiguously demonstrate that this method allows the highly pure heteropoly acid nanocrystals with intact Keggin-type structure controlled directionally self-assembly within mesopores of silica SBA-15. Such method may open up a new entry to the highly pure multicomponent nanocrystalline particles inside the cavity of the porous materials.
