摘要：

X-ray photoelectron spectroscopy has established that molecular dioxygen states are stabilised at a Mg(0001) surface in the presence of physisorbed carbon dioxide at 80 K. The dioxygen-CO2 complex is highly reactive with low energy reaction pathways to carbonate formation; the latter is subsequently reduced to give surface carbide and oxide at a temperature below 150 K.
