Outline of Final Research Achievements

A novel category of H2-evolving photocatalysts based on semiconducting SWCNTs (s-SWCNTs) for the photocatalytic overall water splitting is described. These CNT-photocatalysts shows H2-evolving activity under visible and even near-IR illumination since s-SWCNTs act as light absorbers.
