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…
Large diameter TiO nanotubes enable integration of conformed hierarchical and blocking layers for enhanced dye-sensitized solar cell efficiency
Abdelhamid Elzarka, Ning Liu, Imgon Hwang +2
In the present work we grow anodic TiO nanotube layer with tube diameter ~ 500 nm and an open tube mouth. We use this morphology in dye-sensitized solar cells (DSSCs) and show…
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…
Noble metal free photocatalytic H generation on black TiO: On the influence of crystal facets vs. crystal damage
Ning Liu, Hans-Georg Steinrueck, Andres Osvet +2
In this study, we investigate noble metal free photocatalytic water splitting on natural anatase single crystal facets and on wafer slices of the [001] plane before and after these…
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…
