v2 Chapter 425： Very high quality (1/2)

He never expected that Qin Luo could successfully prepare graphene.

”Is it the cause of potassium permanganate?”

Li Min asked in astonishment.

”Well, the oxidation reaction of graphite is enhanced by potassium permanganate, so that the planar structure of carbon atoms in the graphite gradually becomes a planar macromolecule with a positive charge.” Qin Luo said with a smile.

Hearing Qin Luo’s words, Li Min suddenly realized that as a double-degree expert in physics and chemistry, his accumulation of knowledge has already reached a terrifying level. It was only unexpected before, but after Qin Luo’s hint, The whole preparation process became clear instantly.

”So sulfate ions and sulfuric acid molecules gradually enter the graphite layer to form a sulfuric acid-graphite interlayer compound?” Li Min asked.

”Well, the reason why the graphene produced by the redox reaction is of low quality is largely due to the fact that sulfate ions float on the surface and do not enter the graphite layer. Instead, potassium permanganate is used as a catalyst to produce planar macromolecules. This problem can be solved directly!” Qin Luo nodded and said.

At this moment, the audience was silent, and everyone including Li Min looked at Qin Luo dumbfounded.

They could hardly believe their ears.

If they hadn't seen it with their own eyes, they wouldn't believe it.

The entire academic circle had no difficulties that could be solved, so Qin Luo solved it with a little potassium permanganate.

After a long while, Li Min was the first to recover. He glanced at Qin Luo and his eyes were full of complexity.

It was the half-year-old child in front of him who had solved the problem that had plagued the physics world for many years.

Thinking of this, Li Min sighed deeply, arched his hand to Qin Luo, and said with a smile: ”Listening to the Lord's words is better than reading for ten years, and I am convinced.”

”Uh...Professor, don't say that, I'm just lucky.” Qin Luo said shyly.
