Mechanistic study of the role of Au, Pd and Au–Pd in the surface reactions of ethanol over TiO2 in the dark and under photo-excitation

In situinfrared spectroscopy (FTIR) and catalytic reactions are employed to explore the photo-oxidation and photo-reforming of ethanol over TiO₂and M/TiO₂(M = Au, Pd and Au–Pd) catalysts.
