Study Shows How Redox Chemistry Determines the Adsorption Strength of Gold Nanoparticles on Modified Oxide

The strong binding of gold on electronically modified calcium oxide can now be understood in detail. In a computational study, researchers Jenni Andersin, Janne Nevalaita, Karoliina Honkala and Hannu Häkkinen at the University of Jyväskylä Nanoscience Center have shown how redox chemistry entirely determines the adsorption strength of gold on the modified oxide where one metal atom is replaced with molybdenum. The study was funded by the Academy of Finland.
