Chapter 880 Unexpected efficient integration method of carbon nanotubes(2/2)

Generally, copper wire is used as a catalyst, and ethanol reacts with oxygen to produce acetaldehyde and water.

In this process, the copper wire first reacts with oxygen to generate copper oxide, and then reacts with ethanol to generate acetaldehyde and copper, thus achieving the catalytic oxidation of ethanol.

Throughout the process, although the copper wire participated in the reaction, the final quality and itself did not change.

The sulfide in Yaochi crystal is different.

In high temperature and high pressure environments, sulfur and carbon will produce relatively stable carbon disulfide, and the physical and chemical properties of carbon disulfide are relatively stable.

Although it is volatile, it does not break down easily under normal conditions.

In other words, in Yaochi Crystal, this reaction is considered irreversible.

Because whether it is Xu Chuan or he, basically when thinking about the formation process, the first instinct will be to exclude sulfide from the catalyst.

However, the Supercomputing Center, which combines chemical material calculation models, gave a different answer, counter-intuitively suggesting that sulfide and carbon disulfide may be the catalytic reason that guides the orderly arrangement of carbon nanotubes.

This really makes people feel quite incredible.

"Could it be a supersaturation effect?"

Staring at the simulation data report in his hand, Zhao Guanggui thought for a while and then raised a possibility.

"Um?"

This chapter is not over yet, please click on the next page to continue reading! Xu Chuan looked over and immediately reacted: "Did you say saturated catalysis?"

Supersaturated catalysis may refer to the process of promoting or accelerating the supersaturated crystallization reaction by adding a catalyst in a supersaturated solution.

This reaction occurs in a solution containing an excess of solute. When the solute concentration exceeds its saturation concentration at that temperature, supersaturation occurs.

The simplest and most understandable thing in daily life is actually a chemistry experiment I did in high school, the preparation of supersaturated sodium chloride solution.

Of course, there is a big difference between supersaturated catalysis and this concept.

Zhao Guanggui nodded and said: "Well, if sulfide, carbon disulfide and carbon nanotubes are oversaturated during the catalytic process, it is not impossible to stably guide the excess carbon nanotubes for vapor deposition."

"Although supersaturated catalysis is rare in materials science, it is not uncommon. For example, supersaturated Fe-N5 multifunctional catalytic sites are used for durable lithium-sulfur batteries."

Xu Chuan didn't pay attention to what Zhao Guanggui said later. He naturally knew these concepts very well. There was only one thing flashing through his mind at this moment.

Lithium-sulfur battery!

He finally remembered that he had seen the familiar picture of the 'material phase representation diagram' there!

That's right, it was the discovery made during the research on the preparation and electrochemical performance of sulfur-multi-walled carbon nanotube composite materials during the development of lithium-sulfur batteries!

Perhaps, he knows how to use supersaturated polysulfide and carbon disulfide as catalysts and guide materials to prepare carbon nanotube integrated transistors on a large scale.

But before the official start, he still needs to make a call to the moon and ask the scientific researchers there to help him determine a situation in the Yaochi crater!
