Fig. 4

a Deconvoluted Mg 1 s in-situ XPS spectra for sequential hydrogen ab/desorption cycles. The blue and green shading describe the deconvoluted peak of pMgHx and pMg, respectively. (See Supplementary Fig. 9 for the full spectra). b The binding energy and (c) relative intensity changes in the deconvoluted Mg 1 s spectra as a function of the hydrogen ab/desorption step. Each shaded region in (b) and (c) emphasizes the gradual trends in binding energy and relative intensity of pMg and pMgHx. Source data are provided as a Source Data file.
