Abstract

Titanium dioxide (TiO₂) is a wide band metal oxide semiconductor with potential use in a variety of applications, such as gas sensors [1], self-cleaning surfaces [2], solar cells [3], photoelectrochemical cells for water splitting [4], etc. Due to its excellent photocatalytic efficiency and stability [5] but also the plethora of geometries that can be grown (nanorods -NRs, nano-wires etc.) [3], it is one of the most studied materials for applications in photocatalysis [5].
