Researchers at the Schulich Faculty of Chemistry have discovered a “new kind” of chemical bond, thereby opening the door to the development of catalysts with special characteristics unknown until now. The Haifa scientists published their findings recently in the journals Nature Chemistry, Chemical and Engineering News and ChemNews Magazine.
“The field of catalysts is very broad,” said Dr. Mark Gandelman from the chemistry faculty.
“They are at the heart of the food, pharmaceutical, automotive and aviation industry. The world market for catalysts is estimated at $500 billion a year.” These substances influence our daily life in many aspects. With the help of catalysts, we prepare innovative materials with special characteristics, and we can’t manage without them. In fact, much of what serves us is done by catalysts.
They are made mostly from a core of metals, surrounded by organic material that holds it together. Between the two, there is a chemical bond, and the type of bond is very important, because it gives the metal special characteristics,” Gendelman continued.
The new bond is based on positively charged nitrogen. Until now, bonds were based on carbon and related substances.
