Using graphite as a catalyst to break down Ozone

In summary, the conversation discusses the possibility of using graphite as a catalyst to break down ozone into oxygen without causing oxidization. The purpose of this would be for an ionic wind "fan" to draw gases from the atmosphere and propel them in a specific direction. It is noted that passing ozone over carbon typically produces carbon dioxide, and graphite is not an ideal catalyst for this process due to its susceptibility to oxidation. However, the potential for neutral catalysts like platinum is mentioned as a possibility.

Can graphite be used as a catalyst to break down ozone into oxygen without serious oxidization?

The applied use for this is to break down ozone at the output of an ionic wind "fan". Similar operation to an ion thruster used by NASA but instead of using stored gasses and propelling them into space, the gasses would be drawn from atmosphere and propelled in a certain direction.

It's not clear why you would think graphite would act to break down ozone. Passing ozone over carbon produces carbon dioxide:

After all, ozone is a powerful oxidizer, and all that graphite is just waiting to be oxidized.

You make a fine point sir! Thanks for the quick reply.

I just thought I would ask the obvious, as I have used graphite before as a catalyst in electrolysis of water. But I had a feeling that would take neutral catalysts like platinum.
 

1. How does graphite act as a catalyst to break down Ozone?

Graphite is a highly porous and conductive material that has the ability to attract and hold oxygen molecules. When ozone molecules come into contact with the graphite surface, the oxygen atoms in the ozone are attracted to the graphite and form a bond. This bond causes the ozone molecule to break down into oxygen and a single oxygen atom, effectively breaking down the ozone.

2. What makes graphite a suitable catalyst for this reaction?

Graphite has a large surface area and its unique structure allows for efficient contact between the ozone molecules and the graphite surface. Additionally, graphite is a stable and inert material, meaning it does not react with the ozone molecules and does not get consumed in the reaction. This makes it a perfect catalyst for this reaction.

3. How does the presence of graphite impact the rate of ozone breakdown?

The presence of graphite as a catalyst significantly increases the rate of ozone breakdown. This is because the graphite provides a surface for the ozone molecules to react on, and its structure allows for efficient contact and bonding between the ozone and graphite. This results in a faster and more efficient breakdown of ozone.

4. Is graphite the only catalyst that can break down ozone?

No, there are other catalysts that can also break down ozone. However, graphite is a commonly used catalyst due to its availability, stability, and effectiveness in this reaction. Other catalysts may have different properties and may not be as suitable for this specific reaction.

5. Are there any potential drawbacks to using graphite as a catalyst for ozone breakdown?

One potential drawback is that graphite can also react with other substances present in the ozone, such as nitrogen oxides, and form harmful byproducts. Additionally, if the graphite is not properly maintained and cleaned, it can become less effective as a catalyst over time. It is important to carefully monitor and control the use of graphite as a catalyst in order to avoid any potential drawbacks.
