The morphologies and structures of modified multiwall carbon nanotubes (MWNTs) were characterized by using Scanning Electronic Microscope (SEM) and Fourier Transformation Infrared (FTIR).
For the particular structures and excellent physical-chemical characteristics, CNTs show the higher tensile strength of 200 GPa，the young's modulus of 1TPa, and the bending strength of 14.2Gpa.
The morphologies and structures of modified CNTs were discussed.
The structures of modified MWNTs a b Fig.3 FTIR of (a) MAH and (b) MAH-g-MWNTs-OH FTIR spectra of MAH and MAH-g-MWNTs-OH were obtained to investigate the structural changes of MWNTs-OH.

XRD and FT-IR results indicated that the substitution of tungsten occurs in the silicate framework structure of SBA-15.
The catalytic epoxidation of alkenes has become a subject of growing interests in the fundamental chemistry and modern industrial processes, since epoxides are key building blocks in organic synthesis [13, 14].
These proved that the pore structure of modified materials were a high degree ordering hexagonal structure.
A distinct groove and a relatively regular hexagonal pore structure were observed from Fig.4, which indicated that the addition of PW did not destroy the order of the mesoporous structure.
This indicated that the primary structure of hetropoly acid was preserved even after supporting on SBA-15.

Firstly, it was decided that the whole sum of analyzed ASC structures will include classes of structures determined by i=2, 3, 4, 5, 6, 7, 8 and 9.
Structures for testing from this set were selected in the following manner.
Then, structures with the identical data sets were omitted.
The rest of 190 structures used for the testing are described in Figure 2.

Compared with SAXRD and BET, the PALS may not only show the mesoporous information but also provide the structure information of microporous.
Many kinds of technical instruments have been used for characterize the pore structure and distribution, such as SAXRD, TEM and nitrogen gas adsorption [1-7].
This research present that the PALS not only show the mesopore information but also provide the structure information of micropore.
The SAXRD, BET and the PALS were used to characterize the mesoporous structure.
