Electrochemical transducer utilizing nanowires surface

Recent research showed the availability of atmospheric pollutant monitoring using a gas sensor with nanostructured surface of sensing electrode which can be prepared through an anodization process. The use of anodization technique for obtaining oxide porous material which can be used e. g. as nano-template was firstly reported in the work of Masuda et al. The aim of presented work is the fabrication of Au nanowires further modified with TiO₂ layer to improve the electrode sensing properties due to increasing its specific surface.
