Abstract

The adsorption and dissociation of molecular O2 on extended gold surfaces, isolated gold nanoparticles of different size and shape, and small gold clusters supported on TiO2 have been investigated by means of DFT calculations. The influence of particle size and morphology on the mode of adsorption and activation of O2 have been analyzed separately, and it has been found that O2 dissociation is very sensitive to the arrangement of the gold surface atoms. The control of this variable through catalyst preparation opens one way to improve the activity of gold catalysts.
