The fabrication of sponge-like vanadium pentoxide (V2O5) nanostructures using vertically aligned carbon nanotubes (VACNTs) as a template is presented. The VACNTs were grown on silicon substrates by chemical vapor deposition using the Fe/Al bilayer ca

The desire to harness solar energy to address current global environmental problems led us to investigate two-dimensional (2D) core–shell hybrid photocatalysts in the form of a 2D-TiO2–surfactant, mainly composed of fatty acids. The bulk products

Within this work, it is studied the photo-thermionic and photocurrent behavior of two kinds of carbon nanotube arrays, grown by chemical vapor deposition. One kind is fabricated by using a co-catalyst bilayer approach and other by a catalyst-free rou

MXenes, a new class of 2-dimensional materials, and in particular Ti3C2Tx-nanoparticles, have attracted considerable attention in energy storage and catalysis lately. Despite having a weakly-bounded multi-layered structure with self-lubricating abili
