Compositional gradients in sputtered Ti-Au alloys: Site-selective Au-decoration of anodic TiO nanotubes towards enhanced photocatalytic H evolution
Seyedsina Hejazi, Marco Altomare, Shiva Mohajernia +1
Au nanoparticles at the TiO surface can enhance the photocatalytic H generation performances owing to their electron transfer co-catalytic ability. Key to maximize the co-c…
Double-Side Cocatalytic Activation of Anodic TiO Nanotube Membranes with Sputter-Coated Pt for Photocatalytic H Generation from Water-Ethanol Mixtures
Gihoon Cha, Marco Altomare, Nhat Truong Nguyen +3
Self-standing TiO nanotube layers in the form of membranes are fabricated by self-organizing anodization of Ti metal and a potential shock technique. The membranes were then de…
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…
Photocatalytic reduction and scavenging of Hg(II) over templated-dewetted Au on TiO nanotubes
Davide Spanua, Alessandro Bestetti, Helga Hildebrand +3
Gold-decorated TiO nanotubes were used for the photocatalytic abatement of Hg(II) in aqueous solutions. The presence of dewetted Au nanoparticles induces a strong enhancement o…
Templated Dewetting-Alloying of NiCu Bilayers on TiO Nanotubes Enables Efficient Noble Metal-Free Photocatalytic Evolution
Davide Spanu, Sandro Recchia, Shiva Mohajernia +5
Photocatalytic evolution reactions on pristine TiO is characterized by low efficiencies due to trapping and recombination of charge carriers, and due to a sluggish kineti…
