Abstract
Thin magnesium–nickel films grown on Mo(110) under ultra-high vacuum conditions werehydrogenated with atomic H and studied by high-resolution core-level photoelectronspectroscopy (PES) and thermal desorption spectroscopy (TDS). We show spectroscopicevidence for reversible hydrogen storage and clear evidence that no Mg segregation or desorptionoccurs when hydrogen is desorbed from the film. During the heat-up of the hydrogenatedMg5Ni1 film (0.7 K s−1) TDS shows that hydrogen desorption starts at 350 K and reaches its maximum at 420 K.Mg desorption starts at 450 K. The stability of the storage can be enhanced by cooling.
