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.

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 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 A3.

The XRD patterns showed four reflection peaks attributed to (100), (110), (200) and (210),
