Pt-Decorated g-CN/TiO Nanotube Arrays with Enhanced Visible-Light Photocatalytic Activity for H Evolution.

Aligned TiO nanotube layers (TiNTs) grown by self-organizing anodization of a Ti-substrate in a fluoride-based electrolyte were decorated with graphitic-phase CN (g-CN) via a facile chemical vapor deposition approach. In comparison with classical TiO nanotubes (anatase), the g-CN/TiNTs show an onset of the photocurrent at 2.4 eV (vs.
