Relying on its unique properties, titaniumdioxide is employed in a versatility of applications, gas sensing being one of them. Low temperature synthesis of doped TiO2-coatings and their nano-structuring enhance these properties. It is reported that the use of one-dimensional (1-D) nanostructures instead of nano-crystalline films yields more than 2-fold increase in efficiency by improving the sensing properties. Nanotubular sensing electrodes improve sensing performance due to offered high surface to volume ratio to enable strong interaction...
