Abstract
Thermal desorption spectroscopy is a very sensitive and accurate technique for studying hydrogen's diffusion and trapping processes in crystalline and non-crystalline materials. The technique involves accurate measurement of the desorption rate of gas atoms, soluted or trapped in the material, while heating the sample at a known rate. This paper reviews the thermal desorption spectroscopy (TDS) applications in quantitative studies of hydrogen trapping and release behavior in different crystalline and non-crystalline materials. It begins with a brief overview of the physical nature of hydrogen trapping and continues with a discussion on the origins of interactions between a hydrogen atom and a trap site. Based on the simple analytical model of Lee and Lee, some examples of the assessment of comprehensive properties of hydrogen evolution and trapping in different crystalline and non-crystalline materials by means of TDS are shown and discussed in detail.
