Notes:
Pt-Nafion (chemically reduced and sputtered Pt) and Pt-CdS-Nafion membranes were studied by x-ray photoelectron spectroscopy. The chemically deposited Pt was completely reduced to Pt0 and was more concentrated in the surface region than in the interior. The sputtered Pt (100 Å thick) was distributed within the first several hundred Ångstoms of the Nafion, probably involving Pt migration into it, during the RF sputtering process. Changes of the Pt(4f7/2) linewidth indicate interactions between CdS and Pt. The relatively high activity of the 100 Å sputtered Pt-CdS-Nafion membrane for the photoassisted production of H2 in aqueous 0.1 M S2- solution is discussed.
