Optimized FTO seeding enables the growth of high efficient Ta-doped TiO nanorod photoanodes
Christopher Schneider, Ning Liu, Patrik Schmuki
Tantalum doped rutile nanorods were hydrothermally grown on FTO substrates using a new seeding approach. This approach allows the incorporation of high concentrations of up to 4.8…
Noble-Metal-Free Photocatalytic Hydrogen Evolution Activity: The Impact of Ball Milling Anatase Nanopowders with TiH2
Xuemei Zhou, Ning Liu, Jochen Schmidt +10
In this work, we demonstrate that a well-established and facile ball milling approach using mixtures of commercial anatase nanoparticles and TiH2 introduces noble-metal-free photoc…
Black and White Anatase, Rutile and Mixed Forms: Band-Edges and Photocatalytic Activity
Xuemei Zhou, Ewa Wierzbicka, Ning Liu +1
Here we investigate the band-level energetics of "black" hydrogenated titania in different polymorphs using in-situ photoelectrochemical measurements and XPS valence band measureme…
Black Magic in Gray Titania: Noble-Metal-Free Photocatalytic H2 Evolution from Hydrogenated Anatase
Ning Liu, Xuemei Zhou, Nhat Truong Nguyen +5
"Black" TiO2 has gained increasing interest because of its outstanding properties and promising applications in a wide range of fields. Among the outstanding features of the materi…
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…
