Abstract

Hydrogen (H)-and water (H2O)-storage and desorption characteristics of 25 nm thick Pt films on Li2ZrO3 composite materials, exposed to normal air at room temperature, have been investigated by means of elastic recoil detection (ERD), Rutherford backscattering spectrometry (RBS), weight gain measurement (WGM), and thermal desorption spectroscopy (TDS) techniques. It was found by the ERD and TDS that H and H2O were absorbed into the Pt-coated Li2ZrO3 in air at room temperature and desorbed from it in vacuum at much low temperatures of approximately 317 and 309 K, respectively. In addition, the WGM and TDS spectra revealed that the absorption and desorption characters of some gases such as CH4, CO, and CO2 including H as well as H2O into the Li2ZrO3 bulk were improved by Pt deposition.
