Plasmonically active nanoparticles offer a promising pathway to extend the absorption range of photocatalysts. While not necessarily catalytically active themselves, these particles allow the absorption of lower energy ...
Assessing the photoelectrochemical properties of C, N, F codoped TiO2 nanotubes of different lengths
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
The aim of this work has been the photoelectrochemical (PEC) study of nanostructured photoanodes based on TiO2. Highly ordered and well adhered TiO2 nanotubes (TNTs) of different lengths (∼2–20 μm) were prepared in a ...
