Abstract
The interactions of D2O with the Fe3O4(111) and the biphase ordered structu res on alpha-Fe2O3(0001) were studied with X-ray photoelectron spectroscopy (XPS), low energy electron diffraction, thermal desorption, and mass spect roscopy of recoiled ions. These studies indicate that D2O is weakly bound t o the surface and that virtually none exists at the surface after a 10 Lang muir dose at 300 K. However, XPS indicates that when the sample is dosed wi th 3 Langmuirs at 85 K, a significant amount of molecular D2O is bound to t he surface, with a lesser amount of hydroxyls present as well.
