Catalyst Discovery
Apr 17, 2018

One day, the Swedish chemist Besse Rieus conducted a busy experiment in a chemistry laboratory. In the evening, his wife, Maria, prepared a banquet for friends and relatives to congratulate her birthday. Berzelius was immersed in the experiment and forgot everything. Until Maria pulled him out of the lab, he suddenly realized that he was rushing home. As soon as he entered the room, the guests congratulated him with a toast. He took care of his hands and took a glass of peach wine. When he took the second glass of wine to himself, he frowned and shouted, "Maria, how do you bring me the vinegar to drink!" Maria and her guests were both choked. Maria carefully looked at the bottle and poured out a cup to taste. It was all right. It was really a nectar! Berzelius handed over the glass of his own wine and Maria took a sip and almost spit it out. He said, "How did the sweet wine turn into acetic acid?" The guests came close together and observed. , guess the strange things that happened in the "God Cup."

Becelius found that there was a small amount of black powder in the original glass. He licked his hand and found that his hands were stained with platinum black that had stained the platinum in the lab. He drank the cup of sour drink with excitement. It turns out that the magic of turning wine into acetic acid is derived from platinum powder, which accelerates the chemical reaction between ethanol (alcohol) and oxygen in the air to produce acetic acid. Later, people called this effect catalytic or catalytic, and Greek means “unbinding.”

In 1836, he also published a paper in the Journal of Physics and Chemistry, which for the first time put forward the concepts of "catalysis" and "catalyst" used in chemical reactions.
