Highly ordered TiO2 nanotube arrays were fabricated by anodization in an ethylene glycol solution containing NH4F. A pair of platinum electrodes was deposited on the surface of the nanotube layer to fabricate a Pt/TiO2 nanotube arrays hydrogen sensor. The subject sensors exhibited a seven order of m...
