Single atoms as catalysts

Nanowerk  September 2, 2019
Researchers in Austria have shown that metal atoms can be placed on a metal oxide surface so that they show exactly the desired chemical behavior. When metal atoms are deposited on a metal oxide surface, they usually have a very strong tendency to clump together and form nanoparticles. Instead of attaching the active metal atoms to a surface, it is also possible to incorporate them into a molecule with cleverly selected neighboring atoms. The molecules and reactants are then dissolved into a liquid where the chemical reactions take place. They have developed a technique to incorporate metal atoms into a solid surface in a well defined way. The technique can be used, for example, to convert carbon monoxide into carbon dioxide…read more. Open Access TECHNICAL ARTICLE
