Abstract

We report the observation of hydrogen production from photodiodes, when irradiated with UV light. These photodiodes were composed of a stainless steel substrate, with a TiO2 photocatalyst deposited suing APCVD on one side and Pt deposited using sputter coating on the other. In contrast similar devices made using a titanium substrate show no measurable H-2 production.
