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 composed of noble metals, which are not efficient enough to compensate for their high cost. To address this issue for the chemical reaction of adding hydrogen, called hydrogenation, to quinoline, a molecule important in pharmaceutical production, researchers based in China have developed a highly effective catalyst comprising synergistic nanoparticles and single atoms of iridium.
"Selective hydrogenation of quinoline and its derivatives to the corresponding products have wide applications in fine chemical and pharmaceutical industry," said co-corresponding author Changyan Cao, researcher in the Institute of Chemistry, Chinese Academy of Sciences and University of Chinese Academy of Sciences .
The researchers focused on single-atom catalysts, which Cao said have become a hot topic in the catalysis field due to how they can merge the advantages of both homogeneous and
