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…
Spaced TiO Nanotube Arrays Allow for High Performance Hierarchical Supercapacitor Structure
Nhat Truong Nguyen, Selda Ozkan, Imgon Hwang +2
In this work we describe the synthesis and electrochemical properties of nitridated hierarchical TiO nanotubes as an electrode for supercapacitors. The hierarchical TiO nan…
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…
Visible Light Triggered Drug Release from TiO2 Nanotube Arrays: A Novel Controllable Antibacterial Platform
Jingwen Xu, Xuemei Zhou, Zhida Gao +2
In this work, we use a double-layered stack of TiO2 nanotubes (TiNTs) to construct a visible-light triggered drug delivery system. Key for visible-light drug release is a hydrophob…
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…
