Semimetallic TiO2 Nanotubes

Orchestrating conductors: A carbo-thermal reduction treatment of a TiO2 nanotube layer in acetylene converts the tube walls into highly conductive and stable oxy carbide compounds. The resulting semimetallic TiO2 nanotube layers (TiOxCy) are electrode materials with properties that differ from other TiO2 nanotubes (see picture). They have a high oxygen overpotential and can be used as a catalyst support, for example, for methanol oxidation.
