CuO/Cu/rGO nanocomposite anodic titania nanotubes for boosted non-enzymatic glucose biosensors

“…21-1272), with weak diffraction peaks at 2y = 47.81, 53.91, and 55.21 while diffraction peaks at 2y = 38.41, 40.31, 53.11, 63.01, 70.81, and 76.41 can be indexed to Ti metal (Fig.1(a)). The coincidence peaks of the anatase phases of TiO 2 annealed at 400 1C agreed with our previous studies 42,43. On the contrary, the slight intensification in diffraction peaks of anatase phases and Ti metal for CuO/Cu nanoparticles ATNT specimen might be attributed to the surface modification of ATNT arrays by electrochemical deposition of CuO/Cu nanoparticles 44,45.…”

Photoelectrochemical Properties of BODIPY-Sensitized Anodic TiO2 Layers Decorated with AuNPs for Enhanced Solar Performance

“…Given their unique geometry, anodic TiO 2 nanotubes show extraordinary chemical, electrical, photocatalytic, and optical properties that make them considered for a variety of applications, for example, dye-sensitized solar cells (DSSCs), , photocatalysis, , photoelectrochemistry, , gas sensors, batteries, biomaterials, and more. Considering the limitations of its effective use in visible light, the engineering of new hybrid materials based on coupling with co-catalyst, doping, defects engineering, and sensitization , (with other semiconductors, polymers, , or dyes) is still broadly exploited. Sensitization of TiO 2 with dyes is often used for creating solar cell systems.…”

Photoelectrocatalytic conversion of biomethane and biogas to hydrogen over a nanostructured Ti/ TiO 2 semiconductor

“…The electrons are transferred to the counter electrode, where they participate in reduction reactions, while the holes move to the semiconductor/electrolyte interface, where they perform oxidation. 20 Among the semiconductor materials available, TiO 2 is still widely used in photoelectrocatalytic processes, [24][25][26][27] due to advantages such as its high availability, nontoxicity, low cost, photostability, and, most importantly, adequate band gap energy levels for action as both an oxidant and a reductant. 28 Various TiO 2 nanostructures have been studied, such as nanopores, 29 nanowires, 30,31 nanorods, 32 and nanotubes.…”
