开场白

I am so honored to be with you to communicate academic questions and ideas.

The tile of my academic presentation is “The preparation and catalytic performance of porous silica nanotube functioned with heteroatoms”

I shall only take ten minutes of your time.

I will talk about the topic on the preparation of porous materials.

P2

First of all, i wanna introduce myself. I come from nanjing university of technology, nanjing city, china.

P3

The content is listed as follows.

P4

All our researches are conducted by the academic thoughts. Generally speaking, we are committed to porous materials. In order to explore high-performance functionalized materials for Pilot experiments and scale-up production; we tune the structure, such as composition and morphology step by step and optimize them further. What’s more, the possible synthesis mechanisms are also investigated. Today, the presentation is based on the right-hand branch.

P5

It is known that mesoporous silica have excellent characters as the catalyst carrier, such as……..

But due to lack of active sites, we have to introduce organic or inorganic species as active sites. And the catalytic performance need to be further improved.

P6

As we know, the three factors including activity, scale and diffusion factor play decisive role in the catalysis, affecting the yield, selectivity, stability strongly. In our presentation, we mainly focus on the influence of scale factor on the catalysis.

P7

Due to lack of active sites for mesoporous silica, two main methods (surface loading, modified framework) are widely reported, by which various organic or inorganic active sites can be immobilized on the surface or incorporated into the framework of mesopoous silica.

P8

Though various morphologies of mesoporos silica were widely synthesized, the synthesis of the mesoporos silica, with three simultaneous characteristics including doped metal, mesoporous structure and specific morphology, is always a challenge, which is rarely reported.

In other words, for our case exploring a proper condition, at which the silicon and metal sources can simultaneously hydrolyze, can ensure a desired material.

P9

Next, let’s look at the synthetic steps. Firstly,…. Then, …. After that, …. At last, we obtained the

products.

P10

In this work, by changing the synthesis conditions, such as …, and so

on, the pure mesoporous silica with different morphologies were synthesized, including nanosphere, nanorod, helix, capsule and nanotube. We will focus on the preparation and catalytic application of mesoporous silica with nanotube morphology.学术会议英文演讲模板

P11

the SEM images of samples: A1, A2, A3 are shown in the figure. It can be seen that sample a1 is nanowire-like with length of about 2μm and diameter of about 100nm. When the amount of ... is 0.04 g, the morphology of sample A2 became to be short and thick rods and the size is about 1μm in length and 400nm in diameter, respectively. With further increasing the amount of ..., the sample A3 and A4 turned to be spherical morphology. It also can be seen that the diameters of samples A3 and A4 are substantially the same about 450nm. However, the spherical morphology of A4 is more regular than that of A

The XRD patterns showed four reflection peaks attributed to (100), (110), (200) and (210), respectively, due to the hexagonal sructure.

P12

Then, we keep the same amount of ..., increasing the amount of ....

We found that the length increased gradually. The XRD patterns also showed the hexagonal sructure of samples B1, B2, B3, B

P13

Moreover, an additional proof of the hexagonal symmetry structure is given by TEM and the FT pattern. The N2 adsorption-desorption isotherms of the samples B1, B2, B3, B4 exhibit a typical type-IV isotherm.

According to the table of structural parameters, we can find that the specific surface area and total pore volume increase gradually, the thickness of wall decrease and there is no obvious change in diameter.

P14

Furthermore, the possible synthesis mechanism of the mesoporous silica nanotube in dual templates system was proposed. We suggest that due to electrostatic repulsion between positively charged ammonium ions from hydrated ammonia molecules and hydrophilic groups of ..., especially in ammonia (NH3, 25wt.%) solution, the high concentrated

ammonium ions provide a crowded and repulsive space to prevent the conjunction of ... molecules, leading to the formation of the rod-like micelles as template to form pore structure instead of sphere-like ones.The role of co-template ... is suggested to tune the length of rod-like micelles by arranging itself along the axis of channel with PEO and PPO part immersed in the hydrophilic and the hydrophobic group of CTA+ respectively. As a result, the mesoporous nanotube with different length will be synthesized. However, the non-polar ... micelles are not affected by positively charged ammonium. When the amount of co-template increased further, the non-polar ... micelles tend to control the morphology of micelles which are sequentially from nanotube, short rod to sphere-like ones. It my be the reason that the non-polar ... micelles would provide stronger attractive force than the electrostatic repulsion derived from the PEO block, ammonium ions and head group of ..., respectively.

P15

In order to investigate the influence of the morphology and structure of mesoporous silica on catalytic

performance, the samples with copper incorporated were

synthesized.

P16

The figure shows the SEM and TEM images of samples a1, a2, a3, from which we can see they represent incremental length in the range of about 0.5, 0 and 5μm, and insignificant change in diameter around

100nm. In XRD patterns, there are also four reflection peaks for the samples with copper incorprated, respectively, which indicates the incorporation of the inorganic copper salt has no obvious effect on the hexagonal sructure and the ordered degree of pore structure. Moreover, the trends in length and the diameter of nanotube are illustrated.学术会议英文演讲模板

P17

The N2 adsorption-desorption isotherms of the samples a1, a2, a3 exhibit a typical type-IV isotherm according to the IUPAC classification and no hysteresis loop at the relative pressure range of 0.2≤p/p0≤0.4, implying the samples not only have ordered mesoporous structure but also the uniform pore size. Moreover, the pore diameters did not change significantly at different weight ratio of . The most probable pore sizes of

samples a1, a2, a3 are determined to be 71, 50, 44 nm, respectively. The structural parameters are listed in following table.

P18

This table summarized the catalytic activity of copper-modified porous silica nanotube in the direct hydroxylation of benzene with H2O2 as oxidant. The catalysts showed high catalytic activity, and direct proportional relationship between the benzene conversion and the length of the silica nanotube. Considering the similar copper content determined by ICP, the variations of catalytic activities were probably caused by different retention time of reagent in the nanotube with different lengths. P19

It is Summary and Future Research

This part of research can be summed up from the following three aspects.
