Researchers Discover How Gold Binds on Modified Calcium 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 Univ. 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 research team applied the so-called Born-Haber cycle to analyze how different terms contribute to adsorption energy. The calculations were done at the supercomputers of the CSC – IT Center of Science by employing quantum mechanical simulation methods.
