Effect of Heat Treatments on TiH₂: Surface Composition and Hydrogen Release

Abstract:

The present work investigates the effect of heat treatments in air on the surface and structure of titanium hydride (TiH₂) and hydrogen desorption. TiH₂ has been heated in air at 440 and 540 °C for increasing time up to 180 min. to obtain the samples representative of 12 different oxidation conditions. The samples have been then examined by Temperature Programmed Desorption (TPD), X-Ray Diffraction (XRD) and Photoelectron Spectroscopy (XPS). Experimental results are presented and discussed.
