Abstract
The adsorption of hydrogen on bimetallic gold–nickel and gold–copper nanoparticles is simulated quantum chemically. We find that the changes in the adsorption properties of the bimetallic nanosystem are due to the change in distances between atoms and the redistribution of the electron density in the cluster. This leads to an increase in the bond energy of the hydrogen atom near the Ni/Cu atoms; and a decrease, near the Au atoms of the bimetal cluster.
