Abstract
Official abstract text for this publication.
An article is provided that includes a substrate, a silicon containing layer on the substrate, and a layer including metallic Pt on the silicon containing layer. The silicon containing layer is a diamond-like glass layer. Optionally, the substrate is a porous membrane. In some cases, the silicon containing layer is a continuous layer.
First claim
Opening claim text (preview).
What is claimed is: 1. An article comprising: a substrate; a silicon containing layer on the substrate, wherein the silicon containing layer is a diamond-like glass layer; and a layer comprising metallic Pt on the silicon containing layer. 2. The article of claim 1 , wherein the silicon containing layer is a continuous layer. 3. The article of claim 1 , wherein the silicon containing layer comprises SiO x C z H y . 4. The article of claim 1 , wherein the substrate is a porous membrane. 5. The article of claim 1 , wherein the substrate comprises a polymer, a nonwoven or a carbon fiber. 6. The article of claim 5 , wherein the polymer is a fluorinated polymer. 7. The article of claim 6 , wherein the fluorinated polymer is polytetrafluoroethylene. 8. The article of claim 5 , wherein the carbon fiber is selected from at least one of carbon nanofibers and carbon microfibers. 9. The article of claim 1 , wherein metallic Pt is distributed throughout the layer comprising metallic Pt. 10. The article of claim 1 , wherein the metallic Pt is collectively present in the article at a concentration in a range from 0.0001 mg/cm 3 to 100 mg/cm 3 . 11. The article of claim 1 , wherein the layer comprising metallic Pt is a discontinuous layer. 12. The article of claim 11 , wherein the discontinuous layer of metallic Pt comprises a plurality of island-like regions of the metallic Pt.
