The hydrogenation reaction of acetonitrile adsorbed on a platinum surface to produce amines has been investigated by theoretical and in situ infrared studies. An energetic, kinetics and vibrational analysis have been performed to unravel the elementary steps of the reaction and to clarify the mechanism. The comparison with the experiments allows us to identify an imine as a crucial intermediate for...
Single atom catalysts hold a great potential in heterogeneous catalysis. In this model study, we report on the observation of Pt single atoms in low-melting-point Pt–Ga alloy prepared on modified highly oriented pyrolytic graphite (HOPG) under ultrahigh vacuum (UHV) conditions. In the first part, we examined the growth of Pt nanoparticles (NP) on HOPG modified by Ar+ bombardment. In the second part,...
