Black TiO2 nanotubes formed by high energy proton implantation show noble-metal-co-catalyst free photocatalytic H2-evolution
Ning Liu, Volker Häublein, Xuemei Zhou +8
We apply high-energy proton ion-implantation to modify TiO2 nanotubes selectively at their tops. In the proton-implanted region we observe the creation of intrinsic co-catalytic ce…
Hydrogenated anatase: Strong photocatalytic H2 evolution without the use of a co-catalyst
Ning Liu, Christopher Schneider, Detlef Freitag +8
In the present work we show, how a high pressure hydrogenation of commercial anatase or anatase/rutile powder can create a photocatalyst for hydrogen evolution that is highly effec…
TiO2 nanotubes: N-ion implantation at low-dose provides noble-metal-free photocatalytic H2-evolution activity
Xuemei Zhou, Volker Häublein, Ning Liu +7
Low-dose nitrogen implantation induces in TiO2 nanotubes a co-catalytic activity for photocatalytic H2-evolution. The use of an ion implantation process leads to a N-implanted zone…
Ar+-ion Bombardment of TiO2 Nanotubes Creates Co-catalytic Effect for Photocatalytic Open Circuit Hydrogen Evolution
Xuemei Zhou, Ning Liu, Patrik Schmuki
In the present work, extended Argon ion bombardment was used to modify anatase TiO2 nanotube (NTs) layers. In situ X-ray photoelectron spectroscopy revealed a high content of sub-o…
