Novel synergistic single-atom catalyst approach breaks activity limitation of predecessors

While the developed synergistic catalyst does not erase the need for noble metals, it does reduce the amount needed for a better reaction

28-Mar-2022

The key to chemical reactions is in the name — there needs to be something that causes the chemicals to react to one another. Called a catalyst, this component induces or speeds up reactions in a controlled manner to produce a desired outcome. The catalysts used in several industries are often ...

When human and machine agree

A human research team and a machine learning algorithm have found that we need to rethink much of what we know about iridium oxide

14-Oct-2020

Iridium oxide is an excellent catalyst for electrochemical reactions, and is typically used for the production of energy carriers such as hydrogen from water. Now it turns out that research on iridium oxide carried out so far has been based on a wrong basic assumption: The arrangement of the ...

New arylation inducing reaction developed

15-Jan-2018

KAIST researchers have identified a reaction mechanism that selectively introduces aryl groups at the desired position of a molecule at room temperature. A team, co-led by Professor Sukbok Chang and Mu-Hyun Baik of the Department of Chemistry, used an iridium catalyst for the reaction. The team ...
