1. Chemistry: a substance that causes or accelerates a chemical reaction without itself being affected. 

2. something that causes activity between two or more persons or forces without itself being affected. 

3. a person or thing that precipitates an event or change. 

4. a person whose talk, enthusiasm, or energy causes others to be more friendly, enthusiastic, or energetic.

Etymology: from catalysis, from Ancient Greek κατάλυσις ‎(katálusis, “dissolution”), from καταλύω ‎(katalúō, “I dissolve”), from κατά ‎(katá, “down”) + λύω ‎(lúō, “I loose”).

Cheap and abundant chemical outperforms precious metals as a catalyst

A team of Caltech chemists has discovered a method for producing a group of silicon-containing organic chemicals without relying on expensive precious metal catalysts. Instead, the new technique uses as a catalyst a cheap, abundant chemical that is commonly found in chemistry labs around the world—potassium tert-butoxide—to help create a host of products ranging from new medicines to advanced materials. And it turns out that the potassium salt is more effective than state-of-the-art precious metal complexes at running very challenging chemical reactions.

“We have shown for the first time that you can efficiently make carbon-silicon bonds with a safe and inexpensive catalyst based on potassium rather than ultrarare precious metals like platinum, palladium, and iridium,” says Anton Toutov, a graduate student working in the laboratory of Bob Grubbs, Caltech’s Victor and Elizabeth Atkins Professor of Chemistry. “We’re very excited because this new method is not only ‘greener’ and more efficient, but it is also thousands of times less expensive than what’s currently out there for making useful chemical building blocks. This is a technology that the chemical industry could readily adopt.”
