BINDING ENERGIES FOR OXYGEN ON TRANSITION METAL SURFACES
Abstract
The binding energies and related energies of associative desorption for oxygen on close-packed (W(110), Mo(110), and Ru(0001)) and furrowed (W(112), Mo(112), and ) surfaces have been calculated by DFT method with generalized gradient approximation for exchange-correlation potential in the revised-Perdew–Burke–Ernzerhof form. The unified approach allows one for a direct comparison of calculated binding energies for different transition metals and different surface geometries, thus revealing the trends that are essential for catalytic properties of surfaces with adsorbed oxygen layers.
