Establishing High Photocatalytic H₂ Evolution from Multiwalled Titanate Nanotubes

Black TiO 2 in various forms has been investigated for numerous photochemical applications. In photocatalytic water splitting, “grey” titania forms have been reported to reach considerable H 2 generation rates without using a noble metal co‐catalyst. Up to now, a variety of anatase powders or other morphologies has been investigated in grey and black forms. Here we describe that hydrothermal titanate/anatase nanotubes can show a strong noble...
