Advantage of carbon nanotubes as a catalyst:

1. A high specific surface area

2. Active substance is highly fragmented, a few nanometers

3. Active substance on the outer surface of thetube, the diffusion of the reactant molecules small resistance

4. High thermal conductivity, the heat of reaction is easy to export.

 

Application of carbon nanotubes as a catalyst support:

1. Supported metal catalysts

2. Supported metal oxide catalysts

3. Load alloy catalyst

 

Supported metal catalysts advantages:

1. To improve the physical properties ofelectrical conductivity, corrosion resistance, lubricity, hardness, etc.

2. Binding force between carbon nanotubes andmetal matrix reinforced

3. Make metal catalyst has a high catalyticactivity

 

The transition metal catalyst used directly forthe synthesis of carbon nanotubes, purification and chemical separation method,and for the purified carbon nanotubes - xylene hydrogenation and cracking reactions, and found to have good catalytic cracking activity. The reason is the inner wall due to trace amounts of carbon nanotubes dispersed in the form ofhigh, the high dispersion of the metal components be measured easily, but it shows a high activity, and difficult to produce carbon, not inactivated. Butthis method is difficult to control the amount of active ingredient loading on carbon nanotubes.

If this method can be combined together and impregnation method suitable catalyst may be complementary, after all, a good idea.
