Dewetted Au nanoparticles on TiO surfaces -- Evidence of a size-independent plasmonic photo-electrochemical response
Markus Licklederer, Nhat Truong Nguyen, Reza Mohammadi +6
Flat TiO layers are deposited by magnetron sputtering on Ti/Si wafers. The TiO surfaces are then sputter-coated with thin Au films of a nominal thickness of 0.5-10 nm that…
Enhanced Solar Water Splitting by Swift Charge Separation in Au/FeOOH Sandwiched Single Crystalline FeO Nanoflake Photoelectrodes
Lei Wang, Nhat Truong Nguyen, Yajun Zhang +2
In this work, single crystalline -FeO nanoflakes (NFs) are formed in a highly dense array by Au seeding of a Fe substrate by a thermal oxidation technique. The NFs are c…
Highly Conducting Spaced TiO Nanotubes Enable Defined Conformal Coating with Nanocrystalline NbO and High Performance Supercapacitor Applications
Selda Ozkan, Nhat Truong Nguyen, Imgon Hwang +2
In this work, we report on the electrochemical behavior of nitrided spaced TiO nanotubes conformally coated with a nanocrystalline NbO layer and find for these hierarch…
Nanoporous AuPt and AuPtAg alloy co-catalysts formed by dewetting-dealloying on ordered TiO2 nanotube surface lead to significantly enhanced photocatalytic H2 generation
Nhat Truong Nguyen, Selda Ozkan, Ondrej Tomanec +3
Effective co-catalysts are of key importance for photocatalytic H2 generation from aqueous environments. An attractive co-catalyst candidate are AuPt (metastable) alloys due to the…
Amorphous Mo-Ta oxide nanotubes for long-term stable Mo oxide based supercapacitors
Bowen Jin, Seyedsina Hejazi, Florian Pyczak +8
With a large-scale usage of portable electric appliances, a high demand for increasingly high density energy storage devices has emerged. MoO3 has, in principle, a large potential…
Forming a highly active, homogeneously alloyed AuPt co-catalyst decoration on O2 nanotubes directly during anodic growth
Haidong Bian, Nhat Truong Nguyen, JeongEun Yoo +10
Au and Pt do not form homogeneous bulk alloys as they are thermodynamically not miscible. However, we show that anodic TiO nanotubes (NTs) can in-situ be uniformly decorated wi…
