The chemical surface structure of Ti decorated single walled carbon nanotubes SWNTs is studied. X ray photoelectron spectra show that Ti adatoms on the SWNT surface oxidize even under ultrahigh vacuum conditions, presenting a serious obstacle for the use of Ti decorated SWNTs for hydrogen storage. A subsequent deposition of Li can, however, reduce the degree of Ti oxidation, liberating Ti atoms for the interaction with hydrogen molecules in hydrogen storage applications
