Effect of Low Oxygen Annealing on Photoelectrochemical Water Splitting Properties of -FeO
Yoichi Makimizu, Nhat Truong Nguyen, Hyo-Jin Ahn +4
Photoelectrochemical (PEC) water splitting is a promising method for conversing solar energy into chemical energy stored in the form of hydrogen. Nanostructured hematite (-Fe$_2…
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 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…
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…
Noble metals on anodic TiO2 nanotubes mouths: Thermal dewetting of minimal Pt co-catalyst loading leads to significantly enhanced photocatalytic H2 generation
Nhat Truong Nguyen, Marco Altomare, JeongEun Yoo +2
The least is the best. We introduce a technique to strongly reduce Pt use for photocatalytic hydrogen generation from TiO2 nanotubes. By site-selectively depositing thin layers of…
Suspended Pt nanoparticles over TiO2 nanotubes for enhanced photocatalytic H2 evolution
Nhat Truong Nguyen, JeongEun Yoo, Marco Altomare +1
In the present work we introduce a technique to form a photocatalyst, based on Pt nanoparticles suspended over the mouth of TiO2 nanotubes. These structures are obtained by the dec…
